Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 57, 13, 221 i.e. 12597 smallest integer divisible by all numbers.
Least common multiple (LCM) of 57, 13, 221 is 12597.
LCM(57, 13, 221) = 12597
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
13 | 57, 13, 221 |
57, 1, 17 |
∴ So the LCM of the given numbers is 13 x 57 x 1 x 17 = 12597
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 57,13,221 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,13,221) = 1
common factors(in case of two or more numbers have common factors) = 13
GCF(57,13,221) x common factors =1 x 13 = 13
LCM(57,13,221) = ( 57 × 13 × 221 ) / 13
LCM(57,13,221) = 163761 / 13
LCM(57,13,221) = 12597
∴ Least Common Multiple of 57,13,221 is 12597
