Find LCM of 780,752,718,996,624 with Prime Factorization
| 2 | 780, 752, 718, 996, 624 |
| 2 | 390, 376, 359, 498, 312 |
| 2 | 195, 188, 359, 249, 156 |
| 2 | 195, 94, 359, 249, 78 |
| 3 | 195, 47, 359, 249, 39 |
| 13 | 65, 47, 359, 83, 13 |
| 5, 47, 359, 83, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 13 x 5 x 47 x 359 x 83 x 1 = 4369432080
Therefore, the lowest common multiple of 780,752,718,996,624 is 4369432080.
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.
780 x 752 x 718 x 996 x 624 = 261746459320320
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.
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
718 : 1, 2, 359, 718
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,752,718,996,624, is 2.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
752:2x 2x 2x 2x 47
718:2x 359
996:2x 2x 3x 83
624:2x 2x 2x 2x 3x 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 2x 2x 2x 2x 3x 3x 13 = 29952
Therefore, the value for common factors is 29952.
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 = 261746459320320/(2x29952)
LCM = 261746459320320/59904
LCM = 4369432080
Thus, we can understand that the LCM of 780,752,718,996,624 is 4369432080.
