Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 768, 561, 693, 730, 438 i.e. 1100816640 smallest integer divisible by all numbers.
Least common multiple (LCM) of 768, 561, 693, 730, 438 is 1100816640.
LCM(768, 561, 693, 730, 438) = 1100816640
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 768, 561, 693, 730, 438 |
3 | 384, 561, 693, 365, 219 |
11 | 128, 187, 231, 365, 73 |
73 | 128, 17, 21, 365, 73 |
128, 17, 21, 5, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 11 x 73 x 128 x 17 x 21 x 5 x 1 = 1100816640
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 768,561,693,730,438 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(768,561,693,730,438) = 1
common factors(in case of two or more numbers have common factors) = 86724
GCF(768,561,693,730,438) x common factors =1 x 86724 = 86724
LCM(768,561,693,730,438) = ( 768 × 561 × 693 × 730 × 438 ) / 86724
LCM(768,561,693,730,438) = 95467222287360 / 86724
LCM(768,561,693,730,438) = 1100816640
∴ Least Common Multiple of 768,561,693,730,438 is 1100816640
