Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 688, 252, 938, 445, 272 i.e. 21969123120 smallest integer divisible by all numbers.
Least common multiple (LCM) of 688, 252, 938, 445, 272 is 21969123120.
LCM(688, 252, 938, 445, 272) = 21969123120
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 688, 252, 938, 445, 272 |
2 | 344, 126, 469, 445, 136 |
2 | 172, 63, 469, 445, 68 |
2 | 86, 63, 469, 445, 34 |
7 | 43, 63, 469, 445, 17 |
43, 9, 67, 445, 17 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 7 x 43 x 9 x 67 x 445 x 17 = 21969123120
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 688,252,938,445,272 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(688,252,938,445,272) = 1
common factors(in case of two or more numbers have common factors) = 896
GCF(688,252,938,445,272) x common factors =1 x 896 = 896
LCM(688,252,938,445,272) = ( 688 × 252 × 938 × 445 × 272 ) / 896
LCM(688,252,938,445,272) = 19684334315520 / 896
LCM(688,252,938,445,272) = 21969123120
∴ Least Common Multiple of 688,252,938,445,272 is 21969123120
