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