The LCM of 712,352,979,858 is 1221792.
Find LCM of 712,352,979,858 with Prime Factorization
| 2 | 712, 352, 979, 858 |
| 2 | 356, 176, 979, 429 |
| 2 | 178, 88, 979, 429 |
| 11 | 89, 44, 979, 429 |
| 89 | 89, 4, 89, 39 |
| 1, 4, 1, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 89 x 1 x 4 x 1 x 39 = 1221792
Therefore, the lowest common multiple of 712,352,979,858 is 1221792.
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.
712 x 352 x 979 x 858 = 210519648768
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.
712 : 1, 2, 4, 8, 89, 178, 356, 712
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
979 : 1, 11, 89, 979
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 712,352,979,858, is 1.
Now, the common factors can be found like this.
712:2x 2x 2x 89
352:2x 2x 2x 2x 2x 11
979:11x 89
858:2x 3x 11x 13
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 11x 11x 89 = 172304
Therefore, the value for common factors is 172304.
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 = 210519648768/(1x172304)
LCM = 210519648768/172304
LCM = 1221792
Thus, we can understand that the LCM of 712,352,979,858 is 1221792.
