Find LCM of 493,638,715,390 with Prime Factorization
| 2 | 493, 638, 715, 390 |
| 5 | 493, 319, 715, 195 |
| 11 | 493, 319, 143, 39 |
| 13 | 493, 29, 13, 39 |
| 29 | 493, 29, 1, 3 |
| 17, 1, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 13 x 29 x 17 x 1 x 1 x 3 = 2114970
Therefore, the lowest common multiple of 493,638,715,390 is 2114970.
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.
493 x 638 x 715 x 390 = 87707805900
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.
493 : 1, 17, 29, 493
638 : 1, 2, 11, 22, 29, 58, 319, 638
715 : 1, 5, 11, 13, 55, 65, 143, 715
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,638,715,390, is 1.
Now, the common factors can be found like this.
493:17x 29
638:2x 11x 29
715:5x 11x 13
390:2x 3x 5x 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 5x 11x 13x 29 = 41470
Therefore, the value for common factors is 41470.
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 = 87707805900/(1x41470)
LCM = 87707805900/41470
LCM = 2114970
Thus, we can understand that the LCM of 493,638,715,390 is 2114970.
