Given numbers are 151,704,561,638,539
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 151,704,561,638,539 is 7703957184.
Find LCM of 151,704,561,638,539 with Prime Factorization
| 2 | 151, 704, 561, 638, 539 |
| 11 | 151, 352, 561, 319, 539 |
| 151, 32, 51, 29, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 151 x 32 x 51 x 29 x 49 = 7703957184
Therefore, the lowest common multiple of 151,704,561,638,539 is 7703957184.
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.
151 x 704 x 561 x 638 x 539 = 20507934023808
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.
151 : 1, 151
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
561 : 1, 3, 11, 17, 33, 51, 187, 561
638 : 1, 2, 11, 22, 29, 58, 319, 638
539 : 1, 7, 11, 49, 77, 539
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 151,704,561,638,539, is 1.
Now, the common factors can be found like this.
151:151
704:2x 2x 2x 2x 2x 2x 11
561:3x 11x 17
638:2x 11x 29
539:7x 7x 11
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 11x 11 = 2662
Therefore, the value for common factors is 2662.
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 = 20507934023808/(1x2662)
LCM = 20507934023808/2662
LCM = 7703957184
Thus, we can understand that the LCM of 151,704,561,638,539 is 7703957184.
