Find LCM of 472,647,704,852,990 with Prime Factorization
| 2 | 472, 647, 704, 852, 990 |
| 2 | 236, 647, 352, 426, 495 |
| 2 | 118, 647, 176, 213, 495 |
| 3 | 59, 647, 88, 213, 495 |
| 11 | 59, 647, 88, 71, 165 |
| 59, 647, 8, 71, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 59 x 647 x 8 x 71 x 15 = 85861765440
Therefore, the lowest common multiple of 472,647,704,852,990 is 85861765440.
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.
472 x 647 x 704 x 852 x 990 = 181340048609280
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.
472 : 1, 2, 4, 8, 59, 118, 236, 472
647 : 1, 647
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 472,647,704,852,990, is 1.
Now, the common factors can be found like this.
472:2x 2x 2x 59
647:647
704:2x 2x 2x 2x 2x 2x 11
852:2x 2x 3x 71
990:2x 3x 3x 5x 11
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 2x 3x 11 = 2112
Therefore, the value for common factors is 2112.
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 = 181340048609280/(1x2112)
LCM = 181340048609280/2112
LCM = 85861765440
Thus, we can understand that the LCM of 472,647,704,852,990 is 85861765440.
