LCM of 510 and 92: How to find LCM of 510 and 92?

The LCM of 510 and 92 is 23460. The Least Common Multiple (LCM) of two numbers is the smallest number that is a multiple of both. The LCM of 510 and 92 is the smallest number that both 510 and 92 go into evenly. In this blog, we will explore easy ways to find the LCM of 510 and 92.

Methods to find the LCM of 510 and 92

Here are three simple methods to calculate the LCM of 510 and 92:

1. Prime Factorization Method

In this method, we break each number into its prime factors and use the highest powers of each factor.

• Prime factorization of 510: 2 × 3 × 5 × 17
• Prime factorization of 92: 2 × 2 × 23
• Taking the highest powers of all factors: 2² × 3 × 5 × 17 × 23 = 23460

Thus, LCM(510,92) = 23,460.

2. Listing Multiples Method

We list the multiples of both numbers and find the smallest one that appears in both lists.

• Multiples of 510: 510, 1020, 1530, 2040, 2550, ..., 23460,...
• Multiples of 92: 92, 184, 276, 368, 460, ..., 23460, ...
• The smallest common multiple is 23,460.

Thus, LCM(510,92) = 23,460.

3. Division Method

In this method, we divide both numbers by their common factors until at least 2 numbers are divisible.

1. Divide 510 and 92 by 2 → (255, 46)
2. Divide 255 and 46 by 2 → (255, 23)
3. Divide 255 and 23 by 3 → (85, 23)
4. Both 85 and 23 are not divisible by a common number
5. Multiply the divisors: 2 × 2 × 3 × 23 × 85 = 23,460

Thus, LCM(510,92) = 23,460.
