LCM for 24 and 1,000
What's the Least Common Multiple (LCM) of 24 and 1,000?
Answer
(Three thousand)
Finding LCM for 24 and 1,000 using GCF of these numbers
The first method to find LCM for numbers 24 and 1,000 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 24 and 1,000 is 8, so
LCM = (24 × 1,000) ÷ 8
LCM = 24,000 ÷ 8
LCM = 3,000
