What's the Least Common Multiple (LCM) of 70 and 205?

Answer

LCM of 70 and 205 is 2,870

(Two thousand, eight hundred seventy)

Finding LCM for 70 and 205 using GCF of these numbers

The first method to find LCM for numbers 70 and 205 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 70 and 205 is 5, so

LCM = (70 × 205) ÷ 5

LCM = 14350 ÷ 5

LCM = 2870

Finding LCM for 70 and 205 by Listing Multiples

The second method to find LCM for numbers 70 and 205 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

Multiples of 205: 205, 410, 615, 820, 1025, 1230, 1435, 1640, 1845, 2050, 2255, 2460, 2665, 2870, 3075, 3280

So the LCM for 70 and 205 is 2870

Finding LCM for 70 and 205 by Prime Factorization

Another method to find LCM for numbers 70 and 205 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 205: 5, 41 (exponent form: 51, 411)

21 × 51 × 71 × 411 = 2870
