Find LCM of 724,678,869,792,640 with Prime Factorization
| 2 | 724, 678, 869, 792, 640 |
| 2 | 362, 339, 869, 396, 320 |
| 2 | 181, 339, 869, 198, 160 |
| 3 | 181, 339, 869, 99, 80 |
| 11 | 181, 113, 869, 33, 80 |
| 181, 113, 79, 3, 80 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 181 x 113 x 79 x 3 x 80 = 102376264320
Therefore, the lowest common multiple of 724,678,869,792,640 is 102376264320.
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.
724 x 678 x 869 x 792 x 640 = 216218670243840
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.
724 : 1, 2, 4, 181, 362, 724
678 : 1, 2, 3, 6, 113, 226, 339, 678
869 : 1, 11, 79, 869
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,678,869,792,640, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
678:2x 3x 113
869:11x 79
792:2x 2x 2x 3x 3x 11
640:2x 2x 2x 2x 2x 2x 2x 5
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 = 216218670243840/(1x2112)
LCM = 216218670243840/2112
LCM = 102376264320
Thus, we can understand that the LCM of 724,678,869,792,640 is 102376264320.
