Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 81, 77, 90, 847 i.e. 686070 smallest integer divisible by all numbers.
Least common multiple (LCM) of 81, 77, 90, 847 is 686070.
LCM(81, 77, 90, 847) = 686070
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
3 | 81, 77, 90, 847 |
3 | 27, 77, 30, 847 |
7 | 9, 77, 10, 847 |
11 | 9, 11, 10, 121 |
9, 1, 10, 11 |
∴ So the LCM of the given numbers is 3 x 3 x 7 x 11 x 9 x 1 x 10 x 11 = 686070
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 81,77,90,847 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,77,90,847) = 1
common factors(in case of two or more numbers have common factors) = 693
GCF(81,77,90,847) x common factors =1 x 693 = 693
LCM(81,77,90,847) = ( 81 × 77 × 90 × 847 ) / 693
LCM(81,77,90,847) = 475446510 / 693
LCM(81,77,90,847) = 686070
∴ Least Common Multiple of 81,77,90,847 is 686070
