Given numbers are 916,458,647,636
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 916,458,647,636 is 94231668.
Find LCM of 916,458,647,636 with Prime Factorization
| 2 | 916, 458, 647, 636 |
| 2 | 458, 229, 647, 318 |
| 229 | 229, 229, 647, 159 |
| 1, 1, 647, 159 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 229 x 1 x 1 x 647 x 159 = 94231668
Therefore, the lowest common multiple of 916,458,647,636 is 94231668.
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 458 x 647 x 636 = 172632415776
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
458 : 1, 2, 229, 458
647 : 1, 647
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,458,647,636, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
458:2x 229
647:647
636:2x 2x 3x 53
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 229 = 1832
Therefore, the value for common factors is 1832.
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 = 172632415776/(1x1832)
LCM = 172632415776/1832
LCM = 94231668
Thus, we can understand that the LCM of 916,458,647,636 is 94231668.
