Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 421, 520, 454 i.e. 49694840 smallest integer divisible by all numbers.
Least common multiple (LCM) of 421, 520, 454 is 49694840.
LCM(421, 520, 454) = 49694840
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 421, 520, 454 |
421, 260, 227 |
∴ So the LCM of the given numbers is 2 x 421 x 260 x 227 = 49694840
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 421,520,454 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(421,520,454) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(421,520,454) x common factors =1 x 2 = 2
LCM(421,520,454) = ( 421 × 520 × 454 ) / 2
LCM(421,520,454) = 99389680 / 2
LCM(421,520,454) = 49694840
∴ Least Common Multiple of 421,520,454 is 49694840
