The LCM of 632,974,920,920 is 35395160.
Find LCM of 632,974,920,920 with Prime Factorization
| 2 | 632, 974, 920, 920 |
| 2 | 316, 487, 460, 460 |
| 2 | 158, 487, 230, 230 |
| 5 | 79, 487, 115, 115 |
| 23 | 79, 487, 23, 23 |
| 79, 487, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 23 x 79 x 487 x 1 x 1 = 35395160
Therefore, the lowest common multiple of 632,974,920,920 is 35395160.
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.
632 x 974 x 920 x 920 = 521016755200
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.
632 : 1, 2, 4, 8, 79, 158, 316, 632
974 : 1, 2, 487, 974
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 632,974,920,920, is 2.
Now, the common factors can be found like this.
632:2x 2x 2x 79
974:2x 487
920:2x 2x 2x 5x 23
920:2x 2x 2x 5x 23
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 5x 23 = 7360
Therefore, the value for common factors is 7360.
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 = 521016755200/(2x7360)
LCM = 521016755200/14720
LCM = 35395160
Thus, we can understand that the LCM of 632,974,920,920 is 35395160.
