The LCM of 756,643,396,606 is 540065988.
Find LCM of 756,643,396,606 with Prime Factorization
| 2 | 756, 643, 396, 606 |
| 2 | 378, 643, 198, 303 |
| 3 | 189, 643, 99, 303 |
| 3 | 63, 643, 33, 101 |
| 21, 643, 11, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 21 x 643 x 11 x 101 = 540065988
Therefore, the lowest common multiple of 756,643,396,606 is 540065988.
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.
756 x 643 x 396 x 606 = 116654253408
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
643 : 1, 643
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
606 : 1, 2, 3, 6, 101, 202, 303, 606
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,643,396,606, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
643:643
396:2x 2x 3x 3x 11
606:2x 3x 101
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 116654253408/(1x216)
LCM = 116654253408/216
LCM = 540065988
Thus, we can understand that the LCM of 756,643,396,606 is 540065988.
