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