What's the Least Common Multiple (LCM) of 168 and 189?

Answer

LCM of 168 and 189 is 1,512

(One thousand, five hundred twelve)

Finding LCM for 168 and 189 using GCF of these numbers

The first method to find LCM for numbers 168 and 189 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 168 and 189 is 21, so

LCM = (168 × 189) ÷ 21

LCM = 31752 ÷ 21

LCM = 1512

Finding LCM for 168 and 189 by Listing Multiples

The second method to find LCM for numbers 168 and 189 is to list out the common multiples for both numbers and pick the first one that matches:

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

Multiples of 189: 189, 378, 567, 756, 945, 1134, 1323, 1512, 1701, 1890

So the LCM for 168 and 189 is 1512

Finding LCM for 168 and 189 by Prime Factorization

Another method to find LCM for numbers 168 and 189 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 189: 3, 3, 3, 7 (exponent form: 33, 71)

23 × 33 × 71 = 1512
