Answer: LCM of 168 and 231 is 1,848

(One thousand, eight hundred forty-eight)

Finding LCM for 168 and 231 using GCF's of these numbers

The first method to find LCM for numbers 168 and 231 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 168 and 231 is 21, so

LCM = (168 × 231) ÷ 21

LCM = 38808 ÷ 21

LCM = 1848

Finding LCM for 168 and 231 by Listing Multiples

The second method to find LCM for numbers 168 and 231 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 168: 168, 336, 504, 672, 840, 1008, 1176, 1344, 1512, 1680, 1848, 2016, 2184

Multiples of 231: 231, 462, 693, 924, 1155, 1386, 1617, 1848, 2079, 2310

So the LCM for 168 and 231 is 1848

Finding LCM for 168 and 231 by Prime Factorization

Another method to find LCM for numbers 168 and 231 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 168: 2, 2, 2, 3, 7 (exponent form: 23, 31, 71)

All Prime Factors of 231: 3, 7, 11 (exponent form: 31, 71, 111)

23 × 31 × 71 × 111 = 1848
