What's the Least Common Multiple (LCM) of 70 and 455?

Answer

LCM of 70 and 455 is 910

(Nine hundred ten)

Finding LCM for 70 and 455 using GCF of these numbers

The first method to find LCM for numbers 70 and 455 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 70 and 455 is 35, so

LCM = (70 × 455) ÷ 35

LCM = 31850 ÷ 35

LCM = 910

Finding LCM for 70 and 455 by Listing Multiples

The second method to find LCM for numbers 70 and 455 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

Multiples of 455: 455, 910, 1365, 1820

So the LCM for 70 and 455 is 910

Finding LCM for 70 and 455 by Prime Factorization

Another method to find LCM for numbers 70 and 455 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 455: 5, 7, 13 (exponent form: 51, 71, 131)

21 × 51 × 71 × 131 = 910
