Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 42, 38, 28, 747 i.e. 397404 smallest integer divisible by all numbers.
Least common multiple (LCM) of 42, 38, 28, 747 is 397404.
LCM(42, 38, 28, 747) = 397404
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 42, 38, 28, 747 |
3 | 21, 19, 14, 747 |
7 | 7, 19, 14, 249 |
1, 19, 2, 249 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 19 x 2 x 249 = 397404
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 42,38,28,747 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,38,28,747) = 1
common factors(in case of two or more numbers have common factors) = 84
GCF(42,38,28,747) x common factors =1 x 84 = 84
LCM(42,38,28,747) = ( 42 × 38 × 28 × 747 ) / 84
LCM(42,38,28,747) = 33381936 / 84
LCM(42,38,28,747) = 397404
∴ Least Common Multiple of 42,38,28,747 is 397404
