Find LCM of 638,759,414,913 with Prime Factorization
| 2 | 638, 759, 414, 913 |
| 3 | 319, 759, 207, 913 |
| 11 | 319, 253, 69, 913 |
| 23 | 29, 23, 69, 83 |
| 29, 1, 3, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 23 x 29 x 1 x 3 x 83 = 10961478
Therefore, the lowest common multiple of 638,759,414,913 is 10961478.
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.
638 x 759 x 414 x 913 = 183034759644
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
759 : 1, 3, 11, 23, 33, 69, 253, 759
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
913 : 1, 11, 83, 913
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,759,414,913, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
759:3x 11x 23
414:2x 3x 3x 23
913:11x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11x 11x 23 = 16698
Therefore, the value for common factors is 16698.
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 = 183034759644/(1x16698)
LCM = 183034759644/16698
LCM = 10961478
Thus, we can understand that the LCM of 638,759,414,913 is 10961478.
