Given numbers are 957,667,638,674,520
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 957,667,638,674,520 is 3857207640.
Find LCM of 957,667,638,674,520 with Prime Factorization
| 2 | 957, 667, 638, 674, 520 |
| 11 | 957, 667, 319, 337, 260 |
| 29 | 87, 667, 29, 337, 260 |
| 3, 23, 1, 337, 260 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 3 x 23 x 1 x 337 x 260 = 3857207640
Therefore, the lowest common multiple of 957,667,638,674,520 is 3857207640.
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.
957 x 667 x 638 x 674 x 520 = 142732111510560
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.
957 : 1, 3, 11, 29, 33, 87, 319, 957
667 : 1, 23, 29, 667
638 : 1, 2, 11, 22, 29, 58, 319, 638
674 : 1, 2, 337, 674
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 957,667,638,674,520, is 1.
Now, the common factors can be found like this.
957:3x 11x 29
667:23x 29
638:2x 11x 29
674:2x 337
520:2x 2x 2x 5x 13
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 11x 29x 29 = 37004
Therefore, the value for common factors is 37004.
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 = 142732111510560/(1x37004)
LCM = 142732111510560/37004
LCM = 3857207640
Thus, we can understand that the LCM of 957,667,638,674,520 is 3857207640.
