What's the Least Common Multiple (LCM) of 105 and 245?

Answer

LCM of 105 and 245 is
735

(Seven hundred thirty-five)

Finding LCM for 105 and 245 using GCF of these numbers

The first method to find LCM for numbers 105 and 245 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 105 and 245 is 35, so

LCM = (105 × 245) ÷ 35

LCM = 25,725 ÷ 35

LCM = 735

Finding LCM for 105 and 245 by Listing Multiples

The second method to find LCM for numbers 105 and 245 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 105: 105, 210, 315, 420, 525, 630, 735, 840, 945

Multiples of 245: 245, 490, 735, 980, 1,225

So the LCM for 105 and 245 is 735

Finding LCM for 105 and 245 by Prime Factorization

Another method to find LCM for numbers 105 and 245 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 105: 3, 5, 7 (exponent form: 31, 51, 71)

All Prime Factors of 245: 5, 7, 7 (exponent form: 51, 72)

31 × 51 × 72 = 735
