Find LCM of 792,616,644,947 with Prime Factorization
| 2 | 792, 616, 644, 947 |
| 2 | 396, 308, 322, 947 |
| 2 | 198, 154, 161, 947 |
| 7 | 99, 77, 161, 947 |
| 11 | 99, 11, 23, 947 |
| 9, 1, 23, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 11 x 9 x 1 x 23 x 947 = 120753864
Therefore, the lowest common multiple of 792,616,644,947 is 120753864.
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.
792 x 616 x 644 x 947 = 297537520896
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.
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
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 792,616,644,947, is 1.
Now, the common factors can be found like this.
792:2x 2x 2x 3x 3x 11
616:2x 2x 2x 7x 11
644:2x 2x 7x 23
947:947
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 7x 11 = 2464
Therefore, the value for common factors is 2464.
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 = 297537520896/(1x2464)
LCM = 297537520896/2464
LCM = 120753864
Thus, we can understand that the LCM of 792,616,644,947 is 120753864.
