Given numbers are 916,671,748,656
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 916,671,748,656 is 1713605168.
Find LCM of 916,671,748,656 with Prime Factorization
| 2 | 916, 671, 748, 656 |
| 2 | 458, 671, 374, 328 |
| 11 | 229, 671, 187, 164 |
| 229, 61, 17, 164 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 229 x 61 x 17 x 164 = 1713605168
Therefore, the lowest common multiple of 916,671,748,656 is 1713605168.
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.
916 x 671 x 748 x 656 = 301594509568
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.
916 : 1, 2, 4, 229, 458, 916
671 : 1, 11, 61, 671
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,671,748,656, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
671:11x 61
748:2x 2x 11x 17
656:2x 2x 2x 2x 41
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 2x 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 301594509568/(1x176)
LCM = 301594509568/176
LCM = 1713605168
Thus, we can understand that the LCM of 916,671,748,656 is 1713605168.
