Find LCM of 872,784,730,832,555 with Prime Factorization
| 2 | 872, 784, 730, 832, 555 |
| 2 | 436, 392, 365, 416, 555 |
| 2 | 218, 196, 365, 208, 555 |
| 2 | 109, 98, 365, 104, 555 |
| 5 | 109, 49, 365, 52, 555 |
| 109, 49, 73, 52, 111 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 109 x 49 x 73 x 52 x 111 = 180036991680
Therefore, the lowest common multiple of 872,784,730,832,555 is 180036991680.
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.
872 x 784 x 730 x 832 x 555 = 230447349350400
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.
872 : 1, 2, 4, 8, 109, 218, 436, 872
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
730 : 1, 2, 5, 10, 73, 146, 365, 730
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
555 : 1, 3, 5, 15, 37, 111, 185, 555
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,784,730,832,555, is 1.
Now, the common factors can be found like this.
872:2x 2x 2x 109
784:2x 2x 2x 2x 7x 7
730:2x 5x 73
832:2x 2x 2x 2x 2x 2x 13
555:3x 5x 37
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 2x 2x 5 = 1280
Therefore, the value for common factors is 1280.
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 = 230447349350400/(1x1280)
LCM = 230447349350400/1280
LCM = 180036991680
Thus, we can understand that the LCM of 872,784,730,832,555 is 180036991680.
