Given numbers are 667,572,736,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 667,572,736,920 is 15260960.
Find LCM of 667,572,736,920 with Prime Factorization
| 2 | 667, 572, 736, 920 |
| 2 | 667, 286, 368, 460 |
| 2 | 667, 143, 184, 230 |
| 23 | 667, 143, 92, 115 |
| 29, 143, 4, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 23 x 29 x 143 x 4 x 5 = 15260960
Therefore, the lowest common multiple of 667,572,736,920 is 15260960.
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.
667 x 572 x 736 x 920 = 258337530880
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.
667 : 1, 23, 29, 667
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,572,736,920, is 1.
Now, the common factors can be found like this.
667:23x 29
572:2x 2x 11x 13
736:2x 2x 2x 2x 2x 23
920:2x 2x 2x 5x 23
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 2x 2x 23x 23 = 16928
Therefore, the value for common factors is 16928.
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 = 258337530880/(1x16928)
LCM = 258337530880/16928
LCM = 15260960
Thus, we can understand that the LCM of 667,572,736,920 is 15260960.
