Given numbers are 634,357,943,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 634,357,943,990 is 35217061110.
Find LCM of 634,357,943,990 with Prime Factorization
| 2 | 634, 357, 943, 990 |
| 3 | 317, 357, 943, 495 |
| 317, 119, 943, 165 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 317 x 119 x 943 x 165 = 35217061110
Therefore, the lowest common multiple of 634,357,943,990 is 35217061110.
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 357 x 943 x 990 = 211302366660
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
357 : 1, 3, 7, 17, 21, 51, 119, 357
943 : 1, 23, 41, 943
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,357,943,990, is 1.
Now, the common factors can be found like this.
634:2x 317
357:3x 7x 17
943:23x 41
990:2x 3x 3x 5x 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 3 = 6
Therefore, the value for common factors is 6.
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 = 211302366660/(1x6)
LCM = 211302366660/6
LCM = 35217061110
Thus, we can understand that the LCM of 634,357,943,990 is 35217061110.
