What's the Least Common Multiple (LCM) of 70 and 160?

Answer

LCM of 70 and 160 is 1,120

(One thousand, one hundred twenty)

Finding LCM for 70 and 160 using GCF of these numbers

The first method to find LCM for numbers 70 and 160 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 70 and 160 is 10, so

LCM = (70 × 160) ÷ 10

LCM = 11200 ÷ 10

LCM = 1120

Finding LCM for 70 and 160 by Listing Multiples

The second method to find LCM for numbers 70 and 160 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, 700, 770, 840, 910, 980, 1050, 1120, 1190, 1260

Multiples of 160: 160, 320, 480, 640, 800, 960, 1120, 1280, 1440

So the LCM for 70 and 160 is 1120

Finding LCM for 70 and 160 by Prime Factorization

Another method to find LCM for numbers 70 and 160 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 160: 2, 2, 2, 2, 2, 5 (exponent form: 25, 51)

25 × 51 × 71 = 1120
