(Fifty-one)
Finding LCM for 17 and 51 using GCF's of these numbers
The first method to find LCM for numbers 17 and 51 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 17 and 51 is 17, so
LCM = (17 × 51) ÷ 17
LCM = 867 ÷ 17
LCM = 51
