Find LCM of 132,780,784,979,168 with Prime Factorization
| 2 | 132, 780, 784, 979, 168 |
| 2 | 66, 390, 392, 979, 84 |
| 2 | 33, 195, 196, 979, 42 |
| 3 | 33, 195, 98, 979, 21 |
| 7 | 11, 65, 98, 979, 7 |
| 11 | 11, 65, 14, 979, 1 |
| 1, 65, 14, 89, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 11 x 1 x 65 x 14 x 89 x 1 = 149669520
Therefore, the lowest common multiple of 132,780,784,979,168 is 149669520.
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.
132 x 780 x 784 x 979 x 168 = 13276285102080
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.
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
979 : 1, 11, 89, 979
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 132,780,784,979,168, is 1.
Now, the common factors can be found like this.
132:2x 2x 3x 11
780:2x 2x 3x 5x 13
784:2x 2x 2x 2x 7x 7
979:11x 89
168:2x 2x 2x 3x 7
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 2x 3x 3x 7x 11 = 88704
Therefore, the value for common factors is 88704.
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 = 13276285102080/(1x88704)
LCM = 13276285102080/88704
LCM = 149669520
Thus, we can understand that the LCM of 132,780,784,979,168 is 149669520.
