What's the Least Common Multiple (LCM) of 70 and 145?

Answer

LCM of 70 and 145 is 2,030

(Two thousand, thirty)

Finding LCM for 70 and 145 using GCF of these numbers

The first method to find LCM for numbers 70 and 145 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 70 and 145 is 5, so

LCM = (70 × 145) ÷ 5

LCM = 10150 ÷ 5

LCM = 2030

Finding LCM for 70 and 145 by Listing Multiples

The second method to find LCM for numbers 70 and 145 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

Multiples of 145: 145, 290, 435, 580, 725, 870, 1015, 1160, 1305, 1450, 1595, 1740, 1885, 2030, 2175, 2320

So the LCM for 70 and 145 is 2030

Finding LCM for 70 and 145 by Prime Factorization

Another method to find LCM for numbers 70 and 145 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 145: 5, 29 (exponent form: 51, 291)

21 × 51 × 71 × 291 = 2030
