Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 103, 215, 721 i.e. 155015 smallest integer divisible by all numbers.
Least common multiple (LCM) of 103, 215, 721 is 155015.
LCM(103, 215, 721) = 155015
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
103 | 103, 215, 721 |
1, 215, 7 |
∴ So the LCM of the given numbers is 103 x 1 x 215 x 7 = 155015
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 103,215,721 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(103,215,721) = 1
common factors(in case of two or more numbers have common factors) = 103
GCF(103,215,721) x common factors =1 x 103 = 103
LCM(103,215,721) = ( 103 × 215 × 721 ) / 103
LCM(103,215,721) = 15966545 / 103
LCM(103,215,721) = 155015
∴ Least Common Multiple of 103,215,721 is 155015
