Given numbers are 737,646,989,681,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 737,646,989,681,938 is 2244612873426.
Find LCM of 737,646,989,681,938 with Prime Factorization
| 2 | 737, 646, 989, 681, 938 |
| 67 | 737, 323, 989, 681, 469 |
| 11, 323, 989, 681, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 67 x 11 x 323 x 989 x 681 x 7 = 2244612873426
Therefore, the lowest common multiple of 737,646,989,681,938 is 2244612873426.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
737 x 646 x 989 x 681 x 938 = 300778125039084
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
737 : 1, 11, 67, 737
646 : 1, 2, 17, 19, 34, 38, 323, 646
989 : 1, 23, 43, 989
681 : 1, 3, 227, 681
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 737,646,989,681,938, is 1.
Now, the common factors can be found like this.
737:11x 67
646:2x 17x 19
989:23x 43
681:3x 227
938:2x 7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 67 = 134
Therefore, the value for common factors is 134.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 300778125039084/(1x134)
LCM = 300778125039084/134
LCM = 2244612873426
Thus, we can understand that the LCM of 737,646,989,681,938 is 2244612873426.
