What's the Least Common Multiple (LCM) of 70 and 310?

Answer

LCM of 70 and 310 is 2,170

(Two thousand, one hundred seventy)

Finding LCM for 70 and 310 using GCF of these numbers

The first method to find LCM for numbers 70 and 310 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 70 and 310 is 10, so

LCM = (70 × 310) ÷ 10

LCM = 21700 ÷ 10

LCM = 2170

Finding LCM for 70 and 310 by Listing Multiples

The second method to find LCM for numbers 70 and 310 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

Multiples of 310: 310, 620, 930, 1240, 1550, 1860, 2170, 2480, 2790

So the LCM for 70 and 310 is 2170

Finding LCM for 70 and 310 by Prime Factorization

Another method to find LCM for numbers 70 and 310 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 310: 2, 5, 31 (exponent form: 21, 51, 311)

21 × 51 × 71 × 311 = 2170
