Given numbers are 408,710,638,940,712
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 408,710,638,940,712 is 193271164680.
Find LCM of 408,710,638,940,712 with Prime Factorization
| 2 | 408, 710, 638, 940, 712 |
| 2 | 204, 355, 319, 470, 356 |
| 2 | 102, 355, 319, 235, 178 |
| 5 | 51, 355, 319, 235, 89 |
| 51, 71, 319, 47, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 51 x 71 x 319 x 47 x 89 = 193271164680
Therefore, the lowest common multiple of 408,710,638,940,712 is 193271164680.
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.
408 x 710 x 638 x 940 x 712 = 123693545395200
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
710 : 1, 2, 5, 10, 71, 142, 355, 710
638 : 1, 2, 11, 22, 29, 58, 319, 638
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
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 408,710,638,940,712, is 2.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
710:2x 5x 71
638:2x 11x 29
940:2x 2x 5x 47
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 5 = 320
Therefore, the value for common factors is 320.
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 = 123693545395200/(2x320)
LCM = 123693545395200/640
LCM = 193271164680
Thus, we can understand that the LCM of 408,710,638,940,712 is 193271164680.
