Given numbers are 634,121,771,666,317
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 634,121,771,666,317 is 6565260834.
Find LCM of 634,121,771,666,317 with Prime Factorization
| 2 | 634, 121, 771, 666, 317 |
| 3 | 317, 121, 771, 333, 317 |
| 317 | 317, 121, 257, 111, 317 |
| 1, 121, 257, 111, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 317 x 1 x 121 x 257 x 111 x 1 = 6565260834
Therefore, the lowest common multiple of 634,121,771,666,317 is 6565260834.
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.
634 x 121 x 771 x 666 x 317 = 12487126106268
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.
634 : 1, 2, 317, 634
121 : 1, 11, 121
771 : 1, 3, 257, 771
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
317 : 1, 317
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,121,771,666,317, is 1.
Now, the common factors can be found like this.
634:2x 317
121:11x 11
771:3x 257
666:2x 3x 3x 37
317:317
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 317 = 1902
Therefore, the value for common factors is 1902.
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 = 12487126106268/(1x1902)
LCM = 12487126106268/1902
LCM = 6565260834
Thus, we can understand that the LCM of 634,121,771,666,317 is 6565260834.
