Find LCM of 779,957,649,980,784 with Prime Factorization
| 2 | 779, 957, 649, 980, 784 |
| 2 | 779, 957, 649, 490, 392 |
| 7 | 779, 957, 649, 245, 196 |
| 7 | 779, 957, 649, 35, 28 |
| 11 | 779, 957, 649, 5, 4 |
| 779, 87, 59, 5, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 7 x 11 x 779 x 87 x 59 x 5 x 4 = 172419933840
Therefore, the lowest common multiple of 779,957,649,980,784 is 172419933840.
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.
779 x 957 x 649 x 980 x 784 = 371737377359040
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.
779 : 1, 19, 41, 779
957 : 1, 3, 11, 29, 33, 87, 319, 957
649 : 1, 11, 59, 649
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,957,649,980,784, is 1.
Now, the common factors can be found like this.
779:19x 41
957:3x 11x 29
649:11x 59
980:2x 2x 5x 7x 7
784:2x 2x 2x 2x 7x 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 7x 7x 11 = 2156
Therefore, the value for common factors is 2156.
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 = 371737377359040/(1x2156)
LCM = 371737377359040/2156
LCM = 172419933840
Thus, we can understand that the LCM of 779,957,649,980,784 is 172419933840.
