What's the Least Common Multiple (LCM) of 70 and 245?

Answer

LCM of 70 and 245 is 490

(Four hundred ninety)

Finding LCM for 70 and 245 using GCF of these numbers

The first method to find LCM for numbers 70 and 245 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 70 and 245 is 35, so

LCM = (70 × 245) ÷ 35

LCM = 17150 ÷ 35

LCM = 490

Finding LCM for 70 and 245 by Listing Multiples

The second method to find LCM for numbers 70 and 245 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 70: 70, 140, 210, 280, 350, 420, 490, 560, 630

Multiples of 245: 245, 490, 735, 980

So the LCM for 70 and 245 is 490

Finding LCM for 70 and 245 by Prime Factorization

Another method to find LCM for numbers 70 and 245 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 70: 2, 5, 7 (exponent form: 21, 51, 71)

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

21 × 51 × 72 = 490
