Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 815, 815, 778, 252 i.e. 79892820 smallest integer divisible by all numbers.
Least common multiple (LCM) of 815, 815, 778, 252 is 79892820.
LCM(815, 815, 778, 252) = 79892820
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 815, 815, 778, 252 |
5 | 815, 815, 389, 126 |
163 | 163, 163, 389, 126 |
1, 1, 389, 126 |
∴ So the LCM of the given numbers is 2 x 5 x 163 x 1 x 1 x 389 x 126 = 79892820
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 815,815,778,252 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(815,815,778,252) = 1
common factors(in case of two or more numbers have common factors) = 1630
GCF(815,815,778,252) x common factors =1 x 1630 = 1630
LCM(815,815,778,252) = ( 815 × 815 × 778 × 252 ) / 1630
LCM(815,815,778,252) = 130225296600 / 1630
LCM(815,815,778,252) = 79892820
∴ Least Common Multiple of 815,815,778,252 is 79892820
