Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 38, 61, 665 i.e. 81130 smallest integer divisible by all numbers.
Least common multiple (LCM) of 38, 61, 665 is 81130.
LCM(38, 61, 665) = 81130
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
19 | 38, 61, 665 |
2, 61, 35 |
∴ So the LCM of the given numbers is 19 x 2 x 61 x 35 = 81130
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 38,61,665 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(38,61,665) = 1
common factors(in case of two or more numbers have common factors) = 19
GCF(38,61,665) x common factors =1 x 19 = 19
LCM(38,61,665) = ( 38 × 61 × 665 ) / 19
LCM(38,61,665) = 1541470 / 19
LCM(38,61,665) = 81130
∴ Least Common Multiple of 38,61,665 is 81130
