Given numbers are 716,148,643,666,389
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 716,148,643,666,389 is 59637280356.
Find LCM of 716,148,643,666,389 with Prime Factorization
| 2 | 716, 148, 643, 666, 389 |
| 2 | 358, 74, 643, 333, 389 |
| 37 | 179, 37, 643, 333, 389 |
| 179, 1, 643, 9, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 37 x 179 x 1 x 643 x 9 x 389 = 59637280356
Therefore, the lowest common multiple of 716,148,643,666,389 is 59637280356.
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.
716 x 148 x 643 x 666 x 389 = 17652634985376
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.
716 : 1, 2, 4, 179, 358, 716
148 : 1, 2, 4, 37, 74, 148
643 : 1, 643
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 716,148,643,666,389, is 1.
Now, the common factors can be found like this.
716:2x 2x 179
148:2x 2x 37
643:643
666:2x 3x 3x 37
389:389
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 37 = 296
Therefore, the value for common factors is 296.
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 = 17652634985376/(1x296)
LCM = 17652634985376/296
LCM = 59637280356
Thus, we can understand that the LCM of 716,148,643,666,389 is 59637280356.
