Given numbers are 731,376,226,662,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,376,226,662,989 is 236450096264.
Find LCM of 731,376,226,662,989 with Prime Factorization
| 2 | 731, 376, 226, 662, 989 |
| 43 | 731, 188, 113, 331, 989 |
| 17, 188, 113, 331, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 43 x 17 x 188 x 113 x 331 x 23 = 236450096264
Therefore, the lowest common multiple of 731,376,226,662,989 is 236450096264.
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.
731 x 376 x 226 x 662 x 989 = 40669416557408
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.
731 : 1, 17, 43, 731
376 : 1, 2, 4, 8, 47, 94, 188, 376
226 : 1, 2, 113, 226
662 : 1, 2, 331, 662
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,376,226,662,989, is 1.
Now, the common factors can be found like this.
731:17x 43
376:2x 2x 2x 47
226:2x 113
662:2x 331
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 43 = 172
Therefore, the value for common factors is 172.
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 = 40669416557408/(1x172)
LCM = 40669416557408/172
LCM = 236450096264
Thus, we can understand that the LCM of 731,376,226,662,989 is 236450096264.
