What's the Least Common Multiple (LCM) of 70 and 215?

Answer

LCM of 70 and 215 is 3,010

(Three thousand, ten)

Finding LCM for 70 and 215 using GCF of these numbers

The first method to find LCM for numbers 70 and 215 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 70 and 215 is 5, so

LCM = (70 × 215) ÷ 5

LCM = 15050 ÷ 5

LCM = 3010

Finding LCM for 70 and 215 by Listing Multiples

The second method to find LCM for numbers 70 and 215 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

Multiples of 215: 215, 430, 645, 860, 1075, 1290, 1505, 1720, 1935, 2150, 2365, 2580, 2795, 3010, 3225, 3440

So the LCM for 70 and 215 is 3010

Finding LCM for 70 and 215 by Prime Factorization

Another method to find LCM for numbers 70 and 215 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 215: 5, 43 (exponent form: 51, 431)

21 × 51 × 71 × 431 = 3010
