Find LCM of 758,861,920,392,507 with Prime Factorization
| 2 | 758, 861, 920, 392, 507 |
| 2 | 379, 861, 460, 196, 507 |
| 2 | 379, 861, 230, 98, 507 |
| 3 | 379, 861, 115, 49, 507 |
| 7 | 379, 287, 115, 49, 169 |
| 379, 41, 115, 7, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 379 x 41 x 115 x 7 x 169 = 355152546840
Therefore, the lowest common multiple of 758,861,920,392,507 is 355152546840.
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.
758 x 861 x 920 x 392 x 507 = 119331255738240
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.
758 : 1, 2, 379, 758
861 : 1, 3, 7, 21, 41, 123, 287, 861
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
507 : 1, 3, 13, 39, 169, 507
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 758,861,920,392,507, is 1.
Now, the common factors can be found like this.
758:2x 379
861:3x 7x 41
920:2x 2x 2x 5x 23
392:2x 2x 2x 7x 7
507:3x 13x 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 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 119331255738240/(1x336)
LCM = 119331255738240/336
LCM = 355152546840
Thus, we can understand that the LCM of 758,861,920,392,507 is 355152546840.
