How to Find the Factors of 1920?

To find the factors of 1920, we will have to find the list of numbers that would divide 1920 without leaving any remainder.

• 1920/40 = 48; therefore, 40 is a factor of 1920 and 48 is also a factor of 1920.
• 1920/64 = 30; therefore, 64 is a factor of 1920 and 30 is also a factor of 1920.

Similarly we can find other factors. Hence, the factors of 1920 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 128, 160, 192, 240, 320, 384, 480, 640, 960, 1920.

• Factors of 37 - The factors of 37 are 1, 37
• Factors of 15 - The factors of 15 are 1, 3, 5, 15
• Factors of 22 - The factors of 22 are 1, 2, 11, 22
• Factors of 5 - The factors of 5 are 1, 5

The number 1920 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 1920. The first step is to divide the number 1920 with the smallest prime factor, here it is 2. We keep dividing until it gives a non-zero remainder.

• 1920 ÷ 2 = 960
• 960 ÷ 2 = 480
• 480 ÷ 2 = 240
• 240 ÷ 2 = 120
• 120 ÷ 2 = 60
• 60 ÷ 2 = 30
• 30 ÷ 2 = 15

Further dividing 15 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 15 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 1920 can be written as 2⁷ × 3¹ × 5¹ where 2, 3, 5 are prime.
