Given numbers are 665,988,539,539
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,988,539,539 is 2662660.
Find LCM of 665,988,539,539 with Prime Factorization
| 7 | 665, 988, 539, 539 |
| 7 | 95, 988, 77, 77 |
| 11 | 95, 988, 11, 11 |
| 19 | 95, 988, 1, 1 |
| 5, 52, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 7 x 11 x 19 x 5 x 52 x 1 x 1 = 2662660
Therefore, the lowest common multiple of 665,988,539,539 is 2662660.
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.
665 x 988 x 539 x 539 = 190878107420
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
539 : 1, 7, 11, 49, 77, 539
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 665,988,539,539, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
988:2x 2x 13x 19
539:7x 7x 11
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.
7x 7x 7x 11x 19 = 71687
Therefore, the value for common factors is 71687.
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 = 190878107420/(1x71687)
LCM = 190878107420/71687
LCM = 2662660
Thus, we can understand that the LCM of 665,988,539,539 is 2662660.
