Find LCM of 660,391,495,102,748 with Prime Factorization
| 2 | 660, 391, 495, 102, 748 |
| 2 | 330, 391, 495, 51, 374 |
| 3 | 165, 391, 495, 51, 187 |
| 5 | 55, 391, 165, 17, 187 |
| 11 | 11, 391, 33, 17, 187 |
| 17 | 1, 391, 3, 17, 17 |
| 1, 23, 3, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 17 x 1 x 23 x 3 x 1 x 1 = 774180
Therefore, the lowest common multiple of 660,391,495,102,748 is 774180.
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.
660 x 391 x 495 x 102 x 748 = 9746028151200
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.
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
391 : 1, 17, 23, 391
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
102 : 1, 2, 3, 6, 17, 34, 51, 102
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,391,495,102,748, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
391:17x 23
495:3x 3x 5x 11
102:2x 3x 17
748:2x 2x 11x 17
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 3x 3x 5x 11x 11x 17x 17 = 12588840
Therefore, the value for common factors is 12588840.
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 = 9746028151200/(1x12588840)
LCM = 9746028151200/12588840
LCM = 774180
Thus, we can understand that the LCM of 660,391,495,102,748 is 774180.
