Given numbers are 637,671,832,781,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,671,832,781,946 is 83515816384.
Find LCM of 637,671,832,781,946 with Prime Factorization
| 2 | 637, 671, 832, 781, 946 |
| 11 | 637, 671, 416, 781, 473 |
| 13 | 637, 61, 416, 71, 43 |
| 49, 61, 32, 71, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 49 x 61 x 32 x 71 x 43 = 83515816384
Therefore, the lowest common multiple of 637,671,832,781,946 is 83515816384.
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.
637 x 671 x 832 x 781 x 946 = 262740758344064
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.
637 : 1, 7, 13, 49, 91, 637
671 : 1, 11, 61, 671
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
781 : 1, 11, 71, 781
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,671,832,781,946, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
671:11x 61
832:2x 2x 2x 2x 2x 2x 13
781:11x 71
946:2x 11x 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 11x 11x 13 = 3146
Therefore, the value for common factors is 3146.
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 = 262740758344064/(1x3146)
LCM = 262740758344064/3146
LCM = 83515816384
Thus, we can understand that the LCM of 637,671,832,781,946 is 83515816384.
