What's the Least Common Multiple (LCM) of 70 and 450?

Answer

LCM of 70 and 450 is 3,150

(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

Another method to find LCM for numbers 70 and 450 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 70: 2, 5, 7 (exponent form: 21, 51, 71)

All Prime Factors of 450: 2, 3, 3, 5, 5 (exponent form: 21, 32, 52)

21 × 52 × 71 × 32 = 3150
