How to Find the Factors of 780?

To find the factors of 780, we will have to find the list of numbers that would divide 780 without leaving any remainder.

• 780/15 = 52; therefore, 15 is a factor of 780 and 52 is also a factor of 780.
• 780/26 = 30; therefore, 26 is a factor of 780 and 30 is also a factor of 780.

Similarly we can find other factors. Hence, the factors of 780 are 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780.

• Factors of 72 - The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
• Factors of 39 - The factors of 39 are 1, 3, 13, 39
• Factors of 66 - The factors of 66 are 1, 2, 3, 6, 11, 22, 33, 66

The number 780 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 780. The first step is to divide the number 780 with the smallest prime factor, here it is 2. We keep dividing until it gives a non-zero remainder.

• 780 ÷ 2 = 390
• 390 ÷ 2 = 195

Further dividing 195 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 195 by the next smallest prime factor. We stop ultimately if the next prime factor doesn't exist or when we can't divide any further.

So, the prime factorization of 780 can be written as 2² × 3¹ × 5¹ × 13¹ where 2, 3, 5, 13 are prime.

Pair factors of 780 are the pairs of numbers that when multiplied give the product 780. The factors of 780 in pairs are:

• 1 × 780 = (1, 780)
• 2 × 390 = (2, 390)
• 3 × 260 = (3, 260)
• 4 × 195 = (4, 195)
• 5 × 156 = (5, 156)
• 6 × 130 = (6, 130)
• 10 × 78 = (10, 78)
• 12 × 65 = (12, 65)
• 13 × 60 = (13, 60)
• 15 × 52 = (15, 52)
• 20 × 39 = (20, 39)
• 26 × 30 = (26, 30)

Negative pair factors of 780 are:

• -1 × -780 = (-1, -780)
• -2 × -390 = (-2, -390)
• -3 × -260 = (-3, -260)
• -4 × -195 = (-4, -195)
• -5 × -156 = (-5, -156)
• -6 × -130 = (-6, -130)
• -10 × -78 = (-10, -78)
• -12 × -65 = (-12, -65)
• -13 × -60 = (-13, -60)
• -15 × -52 = (-15, -52)
• -20 × -39 = (-20, -39)
• -26 × -30 = (-26, -30)

NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
