Given numbers are 507,638,913,965
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 507,638,913,965 is 25908009270.
Find LCM of 507,638,913,965 with Prime Factorization
| 11 | 507, 638, 913, 965 |
| 507, 58, 83, 965 |
Multiply the prime numbers at the bottom and the left side.
11 x 507 x 58 x 83 x 965 = 25908009270
Therefore, the lowest common multiple of 507,638,913,965 is 25908009270.
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.
507 x 638 x 913 x 965 = 284988101970
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.
507 : 1, 3, 13, 39, 169, 507
638 : 1, 2, 11, 22, 29, 58, 319, 638
913 : 1, 11, 83, 913
965 : 1, 5, 193, 965
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 507,638,913,965, is 1.
Now, the common factors can be found like this.
507:3x 13x 13
638:2x 11x 29
913:11x 83
965:5x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 284988101970/(1x11)
LCM = 284988101970/11
LCM = 25908009270
Thus, we can understand that the LCM of 507,638,913,965 is 25908009270.
