Given numbers are 637,104,715,716,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,104,715,716,642 is 16104608520.
Find LCM of 637,104,715,716,642 with Prime Factorization
| 2 | 637, 104, 715, 716, 642 |
| 2 | 637, 52, 715, 358, 321 |
| 13 | 637, 26, 715, 179, 321 |
| 49, 2, 55, 179, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 49 x 2 x 55 x 179 x 321 = 16104608520
Therefore, the lowest common multiple of 637,104,715,716,642 is 16104608520.
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.
637 x 104 x 715 x 716 x 642 = 21773430719040
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.
637 : 1, 7, 13, 49, 91, 637
104 : 1, 2, 4, 8, 13, 26, 52, 104
715 : 1, 5, 11, 13, 55, 65, 143, 715
716 : 1, 2, 4, 179, 358, 716
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,104,715,716,642, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
104:2x 2x 2x 13
715:5x 11x 13
716:2x 2x 179
642:2x 3x 107
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 13x 13 = 1352
Therefore, the value for common factors is 1352.
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 = 21773430719040/(1x1352)
LCM = 21773430719040/1352
LCM = 16104608520
Thus, we can understand that the LCM of 637,104,715,716,642 is 16104608520.
