Find LCM of 836,584,657,856 with Prime Factorization
| 2 | 836, 584, 657, 856 |
| 2 | 418, 292, 657, 428 |
| 2 | 209, 146, 657, 214 |
| 73 | 209, 73, 657, 107 |
| 209, 1, 9, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 73 x 209 x 1 x 9 x 107 = 117539928
Therefore, the lowest common multiple of 836,584,657,856 is 117539928.
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.
836 x 584 x 657 x 856 = 274573271808
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.
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
584 : 1, 2, 4, 8, 73, 146, 292, 584
657 : 1, 3, 9, 73, 219, 657
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,584,657,856, is 1.
Now, the common factors can be found like this.
836:2x 2x 11x 19
584:2x 2x 2x 73
657:3x 3x 73
856:2x 2x 2x 107
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 2x 73 = 2336
Therefore, the value for common factors is 2336.
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 = 274573271808/(1x2336)
LCM = 274573271808/2336
LCM = 117539928
Thus, we can understand that the LCM of 836,584,657,856 is 117539928.
