Find LCM of 792,748,662,643 with Prime Factorization
| 2 | 792, 748, 662, 643 |
| 2 | 396, 374, 331, 643 |
| 11 | 198, 187, 331, 643 |
| 18, 17, 331, 643 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 18 x 17 x 331 x 643 = 2865583512
Therefore, the lowest common multiple of 792,748,662,643 is 2865583512.
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 748 x 662 x 643 = 252171349056
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
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
662 : 1, 2, 331, 662
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 792,748,662,643, is 1.
Now, the common factors can be found like this.
792:2x 2x 2x 3x 3x 11
748:2x 2x 11x 17
662:2x 331
643:643
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 11 = 88
Therefore, the value for common factors is 88.
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 = 252171349056/(1x88)
LCM = 252171349056/88
LCM = 2865583512
Thus, we can understand that the LCM of 792,748,662,643 is 2865583512.
