Answer

LCM of 7 and 27 is 189

(One hundred eighty-nine)

Finding LCM for 7 and 27 using GCF of these numbers

The first method to find LCM for numbers 7 and 27 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 7 and 27 is 1, so

LCM = (7 × 27) ÷ 1

LCM = 189 ÷ 1

LCM = 189

Finding LCM for 7 and 27 by Listing Multiples

The second method to find LCM for numbers 7 and 27 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105, 112, 119, 126, 133, 140, 147, 154, 161, 168, 175, 182, 189, 196, 203

Multiples of 27: 27, 54, 81, 108, 135, 162, 189, 216, 243

So the LCM for 7 and 27 is 189

Finding LCM for 7 and 27 by Prime Factorization

Another method to find LCM for numbers 7 and 27 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 7: 7 (exponent form: 71)

All Prime Factors of 27: 3, 3, 3 (exponent form: 33)

71 × 33 = 189
