Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 330, 640, 140 i.e. 147840 smallest integer divisible by all numbers.
Least common multiple (LCM) of 330, 640, 140 is 147840.
LCM(330, 640, 140) = 147840
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 330, 640, 140 |
2 | 165, 320, 70 |
5 | 165, 160, 35 |
33, 32, 7 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 33 x 32 x 7 = 147840
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 330,640,140 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(330,640,140) = 10
common factors(in case of two or more numbers have common factors) = 20
GCF(330,640,140) x common factors =10 x 20 = 200
LCM(330,640,140) = ( 330 × 640 × 140 ) / 200
LCM(330,640,140) = 29568000 / 200
LCM(330,640,140) = 147840
∴ Least Common Multiple of 330,640,140 is 147840
