Given numbers are 416,649,638,377
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 416,649,638,377 is 7829536.
Find LCM of 416,649,638,377 with Prime Factorization
| 2 | 416, 649, 638, 377 |
| 11 | 208, 649, 319, 377 |
| 13 | 208, 59, 29, 377 |
| 29 | 16, 59, 29, 29 |
| 16, 59, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 29 x 16 x 59 x 1 x 1 = 7829536
Therefore, the lowest common multiple of 416,649,638,377 is 7829536.
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.
416 x 649 x 638 x 377 = 64938171584
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.
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
649 : 1, 11, 59, 649
638 : 1, 2, 11, 22, 29, 58, 319, 638
377 : 1, 13, 29, 377
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 416,649,638,377, is 1.
Now, the common factors can be found like this.
416:2x 2x 2x 2x 2x 13
649:11x 59
638:2x 11x 29
377:13x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 13x 29 = 8294
Therefore, the value for common factors is 8294.
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 = 64938171584/(1x8294)
LCM = 64938171584/8294
LCM = 7829536
Thus, we can understand that the LCM of 416,649,638,377 is 7829536.
