Given numbers are 655,657,961,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,657,961,648 is 29775739320.
Find LCM of 655,657,961,648 with Prime Factorization
| 3 | 655, 657, 961, 648 |
| 3 | 655, 219, 961, 216 |
| 655, 73, 961, 72 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 655 x 73 x 961 x 72 = 29775739320
Therefore, the lowest common multiple of 655,657,961,648 is 29775739320.
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.
655 x 657 x 961 x 648 = 267981653880
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.
655 : 1, 5, 131, 655
657 : 1, 3, 9, 73, 219, 657
961 : 1, 31, 961
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,657,961,648, is 1.
Now, the common factors can be found like this.
655:5x 131
657:3x 3x 73
961:31x 31
648:2x 2x 2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 267981653880/(1x9)
LCM = 267981653880/9
LCM = 29775739320
Thus, we can understand that the LCM of 655,657,961,648 is 29775739320.
