What's the Least Common Multiple (LCM) of 70 and 115?

Answer

LCM of 70 and 115 is 1,610

(One thousand, six hundred ten)

Finding LCM for 70 and 115 using GCF of these numbers

The first method to find LCM for numbers 70 and 115 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 70 and 115 is 5, so

LCM = (70 × 115) ÷ 5

LCM = 8050 ÷ 5

LCM = 1610

Finding LCM for 70 and 115 by Listing Multiples

The second method to find LCM for numbers 70 and 115 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

Multiples of 115: 115, 230, 345, 460, 575, 690, 805, 920, 1035, 1150, 1265, 1380, 1495, 1610, 1725, 1840

So the LCM for 70 and 115 is 1610

Finding LCM for 70 and 115 by Prime Factorization

Another method to find LCM for numbers 70 and 115 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 115: 5, 23 (exponent form: 51, 231)

21 × 51 × 71 × 231 = 1610
