Given numbers are 397,628,968,634,717
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,628,968,634,717 is 13713361806408.
Find LCM of 397,628,968,634,717 with Prime Factorization
| 2 | 397, 628, 968, 634, 717 |
| 2 | 397, 314, 484, 317, 717 |
| 397, 157, 242, 317, 717 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 397 x 157 x 242 x 317 x 717 = 13713361806408
Therefore, the lowest common multiple of 397,628,968,634,717 is 13713361806408.
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.
397 x 628 x 968 x 634 x 717 = 109706894451264
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.
397 : 1, 397
628 : 1, 2, 4, 157, 314, 628
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
634 : 1, 2, 317, 634
717 : 1, 3, 239, 717
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,628,968,634,717, is 1.
Now, the common factors can be found like this.
397:397
628:2x 2x 157
968:2x 2x 2x 11x 11
634:2x 317
717:3x 239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2 = 8
Therefore, the value for common factors is 8.
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 = 109706894451264/(1x8)
LCM = 109706894451264/8
LCM = 13713361806408
Thus, we can understand that the LCM of 397,628,968,634,717 is 13713361806408.
