LCM of 8 and 25 by Listing Multiples

To calculate the LCM of 8 and 25 by listing out the common multiples, we can follow the given below steps:

• Step 1: List a few multiples of 8 (8, 16, 24, 32, 40, 48, 56, . . . ) and 25 (25, 50, 75, 100, . . . . )
• Step 2: The common multiples from the multiples of 8 and 25 are 200, 400, . . .
• Step 3: The smallest common multiple of 8 and 25 is 200.

∴ The least common multiple of 8 and 25 = 200.

LCM of 8 and 25 by Division Method

To calculate the LCM of 8 and 25 by the division method, we will divide the numbers(8, 25) by their prime factors (preferably common). The product of these divisors gives the LCM of 8 and 25.

• Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 8 and 25. Write this prime number(2) on the left of the given numbers(8 and 25), separated as per the ladder arrangement.
• Step 2: If any of the given numbers (8, 25) is a multiple of 2, divide it by 2 and write the quotient below it. Bring down any number that is not divisible by the prime number.
• Step 3: Continue the steps until only 1s are left in the last row.

The LCM of 8 and 25 is the product of all prime numbers on the left, i.e. LCM(8, 25) by division method = 2 × 2 × 2 × 5 × 5 = 200.
