Answer: LCM of 65 and 91 is 455

(Four hundred fifty-five)

Finding LCM for 65 and 91 using GCF's of these numbers

The first method to find LCM for numbers 65 and 91 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 65 and 91 is 13, so

LCM = (65 × 91) ÷ 13

LCM = 5915 ÷ 13

LCM = 455

Finding LCM for 65 and 91 by Listing Multiples

The second method to find LCM for numbers 65 and 91 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 65: 65, 130, 195, 260, 325, 390, 455, 520, 585

Multiples of 91: 91, 182, 273, 364, 455, 546, 637

So the LCM for 65 and 91 is 455

Finding LCM for 65 and 91 by Prime Factorization

Another method to find LCM for numbers 65 and 91 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 65: 5, 13 (exponent form: 51, 131)

All Prime Factors of 91: 7, 13 (exponent form: 71, 131)

51 × 131 × 71 = 455
