Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 78, 45, 13, 984 i.e. 191880 smallest integer divisible by all numbers.
Least common multiple (LCM) of 78, 45, 13, 984 is 191880.
LCM(78, 45, 13, 984) = 191880
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 78, 45, 13, 984 |
3 | 39, 45, 13, 492 |
13 | 13, 15, 13, 164 |
1, 15, 1, 164 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 1 x 15 x 1 x 164 = 191880
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 78,45,13,984 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,45,13,984) = 1
common factors(in case of two or more numbers have common factors) = 234
GCF(78,45,13,984) x common factors =1 x 234 = 234
LCM(78,45,13,984) = ( 78 × 45 × 13 × 984 ) / 234
LCM(78,45,13,984) = 44899920 / 234
LCM(78,45,13,984) = 191880
∴ Least Common Multiple of 78,45,13,984 is 191880
