LCM for 70 and 450
What's the Least Common Multiple (LCM) of 70 and 450?
Answer
(Three thousand, one hundred fifty)
Finding LCM for 70 and 450 using GCF of these numbers
The first method to find LCM for numbers 70 and 450 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 70 and 450 is 10, so
LCM = (70 × 450) ÷ 10
LCM = 31500 ÷ 10
LCM = 3150
Finding LCM for 70 and 450 by Listing Multiples
The second method to find LCM for numbers 70 and 450 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 70: 70, 140, 210, 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190, 1260, 1330, 1400, 1470, 1540, 1610, 1680, 1750, 1820, 1890, 1960, 2030, 2100, 2170, 2240, 2310, 2380, 2450, 2520, 2590, 2660, 2730, 2800, 2870, 2940, 3010, 3080, 3150, 3220, 3290
Multiples of 450: 450, 900, 1350, 1800, 2250, 2700, 3150, 3600, 4050
So the LCM for 70 and 450 is 3150
Finding LCM for 70 and 450 by Prime Factorization
