Given numbers are 671,746,836,715,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,746,836,715,634 is 391938172340.
Find LCM of 671,746,836,715,634 with Prime Factorization
| 2 | 671, 746, 836, 715, 634 |
| 11 | 671, 373, 418, 715, 317 |
| 61, 373, 38, 65, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 61 x 373 x 38 x 65 x 317 = 391938172340
Therefore, the lowest common multiple of 671,746,836,715,634 is 391938172340.
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.
671 x 746 x 836 x 715 x 634 = 189698075412560
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.
671 : 1, 11, 61, 671
746 : 1, 2, 373, 746
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
715 : 1, 5, 11, 13, 55, 65, 143, 715
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,746,836,715,634, is 1.
Now, the common factors can be found like this.
671:11x 61
746:2x 373
836:2x 2x 11x 19
715:5x 11x 13
634:2x 317
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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 189698075412560/(1x484)
LCM = 189698075412560/484
LCM = 391938172340
Thus, we can understand that the LCM of 671,746,836,715,634 is 391938172340.
