Find LCM of 568,418,645,771,715 with Prime Factorization
| 2 | 568, 418, 645, 771, 715 |
| 3 | 284, 209, 645, 771, 715 |
| 5 | 284, 209, 215, 257, 715 |
| 11 | 284, 209, 43, 257, 143 |
| 284, 19, 43, 257, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 284 x 19 x 43 x 257 x 13 = 255817830840
Therefore, the lowest common multiple of 568,418,645,771,715 is 255817830840.
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.
568 x 418 x 645 x 771 x 715 = 84419884177200
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.
568 : 1, 2, 4, 8, 71, 142, 284, 568
418 : 1, 2, 11, 19, 22, 38, 209, 418
645 : 1, 3, 5, 15, 43, 129, 215, 645
771 : 1, 3, 257, 771
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 568,418,645,771,715, is 1.
Now, the common factors can be found like this.
568:2x 2x 2x 71
418:2x 11x 19
645:3x 5x 43
771:3x 257
715:5x 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 3x 5x 11 = 330
Therefore, the value for common factors is 330.
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 = 84419884177200/(1x330)
LCM = 84419884177200/330
LCM = 255817830840
Thus, we can understand that the LCM of 568,418,645,771,715 is 255817830840.
