Find LCM of 157,792,403,836,642 with Prime Factorization
| 2 | 157, 792, 403, 836, 642 |
| 2 | 157, 396, 403, 418, 321 |
| 3 | 157, 198, 403, 209, 321 |
| 11 | 157, 66, 403, 209, 107 |
| 157, 6, 403, 19, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 157 x 6 x 403 x 19 x 107 = 101874914856
Therefore, the lowest common multiple of 157,792,403,836,642 is 101874914856.
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.
157 x 792 x 403 x 836 x 642 = 26894977521984
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.
157 : 1, 157
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
403 : 1, 13, 31, 403
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,792,403,836,642, is 1.
Now, the common factors can be found like this.
157:157
792:2x 2x 2x 3x 3x 11
403:13x 31
836:2x 2x 11x 19
642:2x 3x 107
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 11 = 264
Therefore, the value for common factors is 264.
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 = 26894977521984/(1x264)
LCM = 26894977521984/264
LCM = 101874914856
Thus, we can understand that the LCM of 157,792,403,836,642 is 101874914856.
