Answer

LCM of 71 and 142 is 142

(One hundred forty-two)

Finding LCM for 71 and 142 using GCF of these numbers

The first method to find LCM for numbers 71 and 142 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 71 and 142 is 71, so

LCM = (71 × 142) ÷ 71

LCM = 10082 ÷ 71

LCM = 142

Finding LCM for 71 and 142 by Listing Multiples

The second method to find LCM for numbers 71 and 142 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 71: 71, 142, 213, 284

Multiples of 142: 142, 284, 426

So the LCM for 71 and 142 is 142

Finding LCM for 71 and 142 by Prime Factorization

Another method to find LCM for numbers 71 and 142 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 71: 71 (exponent form: 711)

All Prime Factors of 142: 2, 71 (exponent form: 21, 711)

711 × 21 = 142
