What's the Least Common Multiple (LCM) of 154 and 210?

Answer

LCM of 154 and 210 is
2,310

(Two thousand three hundred ten)

Finding LCM for 154 and 210 using GCF of these numbers

The first method to find LCM for numbers 154 and 210 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 154 and 210 is 14, so

LCM = (154 × 210) ÷ 14

LCM = 32,340 ÷ 14

LCM = 2,310

Finding LCM for 154 and 210 by Listing Multiples

The second method to find LCM for numbers 154 and 210 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 154: 154, 308, 462, 616, 770, 924, 1,078, 1,232, 1,386, 1,540, 1,694, 1,848, 2,002, 2,156, 2,310, 2,464, 2,618

Multiples of 210: 210, 420, 630, 840, 1,050, 1,260, 1,470, 1,680, 1,890, 2,100, 2,310, 2,520, 2,730

So the LCM for 154 and 210 is 2,310

Finding LCM for 154 and 210 by Prime Factorization

Another method to find LCM for numbers 154 and 210 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 154: 2, 7, 11 (exponent form: 21, 71, 111)

All Prime Factors of 210: 2, 3, 5, 7 (exponent form: 21, 31, 51, 71)

21 × 71 × 111 × 31 × 51 = 2,310
