Find LCM of 752,715,494,784 with Prime Factorization
| 2 | 752, 715, 494, 784 |
| 2 | 376, 715, 247, 392 |
| 2 | 188, 715, 247, 196 |
| 2 | 94, 715, 247, 98 |
| 13 | 47, 715, 247, 49 |
| 47, 55, 19, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 13 x 47 x 55 x 19 x 49 = 500580080
Therefore, the lowest common multiple of 752,715,494,784 is 500580080.
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.
752 x 715 x 494 x 784 = 208241313280
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.
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
715 : 1, 5, 11, 13, 55, 65, 143, 715
494 : 1, 2, 13, 19, 26, 38, 247, 494
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 752,715,494,784, is 1.
Now, the common factors can be found like this.
752:2x 2x 2x 2x 47
715:5x 11x 13
494:2x 13x 19
784:2x 2x 2x 2x 7x 7
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 13 = 416
Therefore, the value for common factors is 416.
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 = 208241313280/(1x416)
LCM = 208241313280/416
LCM = 500580080
Thus, we can understand that the LCM of 752,715,494,784 is 500580080.
