Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 56, 16, 84, 46 i.e. 7728 smallest integer divisible by all numbers.
Least common multiple (LCM) of 56, 16, 84, 46 is 7728.
LCM(56, 16, 84, 46) = 7728
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 56, 16, 84, 46 |
2 | 28, 8, 42, 23 |
2 | 14, 4, 21, 23 |
7 | 7, 2, 21, 23 |
1, 2, 3, 23 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 1 x 2 x 3 x 23 = 7728
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 56,16,84,46 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(56,16,84,46) = 2
common factors(in case of two or more numbers have common factors) = 224
GCF(56,16,84,46) x common factors =2 x 224 = 448
LCM(56,16,84,46) = ( 56 × 16 × 84 × 46 ) / 448
LCM(56,16,84,46) = 3462144 / 448
LCM(56,16,84,46) = 7728
∴ Least Common Multiple of 56,16,84,46 is 7728
