Given numbers are 658,668,768,920,712
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,668,768,920,712 is 431878352640.
Find LCM of 658,668,768,920,712 with Prime Factorization
| 2 | 658, 668, 768, 920, 712 |
| 2 | 329, 334, 384, 460, 356 |
| 2 | 329, 167, 192, 230, 178 |
| 329, 167, 96, 115, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 329 x 167 x 96 x 115 x 89 = 431878352640
Therefore, the lowest common multiple of 658,668,768,920,712 is 431878352640.
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.
658 x 668 x 768 x 920 x 712 = 221121716551680
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
668 : 1, 2, 4, 167, 334, 668
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
712 : 1, 2, 4, 8, 89, 178, 356, 712
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,668,768,920,712, is 2.
Now, the common factors can be found like this.
658:2x 7x 47
668:2x 2x 167
768:2x 2x 2x 2x 2x 2x 2x 2x 3
920:2x 2x 2x 5x 23
712:2x 2x 2x 89
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 2x 2x 2 = 256
Therefore, the value for common factors is 256.
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 = 221121716551680/(2x256)
LCM = 221121716551680/512
LCM = 431878352640
Thus, we can understand that the LCM of 658,668,768,920,712 is 431878352640.
