Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 16, 76, 42, 285 i.e. 31920 smallest integer divisible by all numbers.
Least common multiple (LCM) of 16, 76, 42, 285 is 31920.
LCM(16, 76, 42, 285) = 31920
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 16, 76, 42, 285 |
2 | 8, 38, 21, 285 |
3 | 4, 19, 21, 285 |
19 | 4, 19, 7, 95 |
4, 1, 7, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 19 x 4 x 1 x 7 x 5 = 31920
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 16,76,42,285 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,76,42,285) = 1
common factors(in case of two or more numbers have common factors) = 456
GCF(16,76,42,285) x common factors =1 x 456 = 456
LCM(16,76,42,285) = ( 16 × 76 × 42 × 285 ) / 456
LCM(16,76,42,285) = 14555520 / 456
LCM(16,76,42,285) = 31920
∴ Least Common Multiple of 16,76,42,285 is 31920
