What's the Least Common Multiple (LCM) of 70 and 350?

Answer

LCM of 70 and 350 is 350

(Three hundred fifty)

Finding LCM for 70 and 350 using GCF of these numbers

The first method to find LCM for numbers 70 and 350 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 70 and 350 is 70, so

LCM = (70 × 350) ÷ 70

LCM = 24500 ÷ 70

LCM = 350

Finding LCM for 70 and 350 by Listing Multiples

The second method to find LCM for numbers 70 and 350 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

Multiples of 350: 350, 700, 1050

So the LCM for 70 and 350 is 350

Finding LCM for 70 and 350 by Prime Factorization

Another method to find LCM for numbers 70 and 350 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 350: 2, 5, 5, 7 (exponent form: 21, 52, 71)

21 × 52 × 71 = 350
