Find LCM of 990,637,419,957,838 with Prime Factorization
| 2 | 990, 637, 419, 957, 838 |
| 3 | 495, 637, 419, 957, 419 |
| 11 | 165, 637, 419, 319, 419 |
| 419 | 15, 637, 419, 29, 419 |
| 15, 637, 1, 29, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 419 x 15 x 637 x 1 x 29 x 1 = 7662785130
Therefore, the lowest common multiple of 990,637,419,957,838 is 7662785130.
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.
990 x 637 x 419 x 957 x 838 = 211906659985020
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.
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
637 : 1, 7, 13, 49, 91, 637
419 : 1, 419
957 : 1, 3, 11, 29, 33, 87, 319, 957
838 : 1, 2, 419, 838
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,637,419,957,838, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
637:7x 7x 13
419:419
957:3x 11x 29
838:2x 419
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11x 419 = 27654
Therefore, the value for common factors is 27654.
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 = 211906659985020/(1x27654)
LCM = 211906659985020/27654
LCM = 7662785130
Thus, we can understand that the LCM of 990,637,419,957,838 is 7662785130.
