Find LCM of 643,592,703,760 with Prime Factorization
| 2 | 643, 592, 703, 760 |
| 2 | 643, 296, 703, 380 |
| 2 | 643, 148, 703, 190 |
| 19 | 643, 74, 703, 95 |
| 37 | 643, 74, 37, 5 |
| 643, 2, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 19 x 37 x 643 x 2 x 1 x 5 = 36162320
Therefore, the lowest common multiple of 643,592,703,760 is 36162320.
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.
643 x 592 x 703 x 760 = 203376887680
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.
643 : 1, 643
592 : 1, 2, 4, 8, 16, 37, 74, 148, 296, 592
703 : 1, 19, 37, 703
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,592,703,760, is 1.
Now, the common factors can be found like this.
643:643
592:2x 2x 2x 2x 37
703:19x 37
760:2x 2x 2x 5x 19
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 19x 37 = 5624
Therefore, the value for common factors is 5624.
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 = 203376887680/(1x5624)
LCM = 203376887680/5624
LCM = 36162320
Thus, we can understand that the LCM of 643,592,703,760 is 36162320.
