Find LCM of 936,677,144,642 with Prime Factorization
| 2 | 936, 677, 144, 642 |
| 2 | 468, 677, 72, 321 |
| 2 | 234, 677, 36, 321 |
| 3 | 117, 677, 18, 321 |
| 3 | 39, 677, 6, 107 |
| 13, 677, 2, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 13 x 677 x 2 x 107 = 135605808
Therefore, the lowest common multiple of 936,677,144,642 is 135605808.
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.
936 x 677 x 144 x 642 = 58581709056
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.
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
677 : 1, 677
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
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 936,677,144,642, is 1.
Now, the common factors can be found like this.
936:2x 2x 2x 3x 3x 13
677:677
144:2x 2x 2x 2x 3x 3
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 2x 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 58581709056/(1x432)
LCM = 58581709056/432
LCM = 135605808
Thus, we can understand that the LCM of 936,677,144,642 is 135605808.
