Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 74, 84, 70, 436 i.e. 1693860 smallest integer divisible by all numbers.
Least common multiple (LCM) of 74, 84, 70, 436 is 1693860.
LCM(74, 84, 70, 436) = 1693860
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 74, 84, 70, 436 |
2 | 37, 42, 35, 218 |
7 | 37, 21, 35, 109 |
37, 3, 5, 109 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 37 x 3 x 5 x 109 = 1693860
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 74,84,70,436 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(74,84,70,436) = 2
common factors(in case of two or more numbers have common factors) = 56
GCF(74,84,70,436) x common factors =2 x 56 = 112
LCM(74,84,70,436) = ( 74 × 84 × 70 × 436 ) / 112
LCM(74,84,70,436) = 189712320 / 112
LCM(74,84,70,436) = 1693860
∴ Least Common Multiple of 74,84,70,436 is 1693860
