Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 85, 21, 28, 75 i.e. 35700 smallest integer divisible by all numbers.
Least common multiple (LCM) of 85, 21, 28, 75 is 35700.
LCM(85, 21, 28, 75) = 35700
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
3 | 85, 21, 28, 75 |
5 | 85, 7, 28, 25 |
7 | 17, 7, 28, 5 |
17, 1, 4, 5 |
∴ So the LCM of the given numbers is 3 x 5 x 7 x 17 x 1 x 4 x 5 = 35700
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 85,21,28,75 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,21,28,75) = 1
common factors(in case of two or more numbers have common factors) = 105
GCF(85,21,28,75) x common factors =1 x 105 = 105
LCM(85,21,28,75) = ( 85 × 21 × 28 × 75 ) / 105
LCM(85,21,28,75) = 3748500 / 105
LCM(85,21,28,75) = 35700
∴ Least Common Multiple of 85,21,28,75 is 35700
