Given numbers are 916,689,583,605
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 916,689,583,605 is 381830020.
Find LCM of 916,689,583,605 with Prime Factorization
| 11 | 916, 689, 583, 605 |
| 53 | 916, 689, 53, 55 |
| 916, 13, 1, 55 |
Multiply the prime numbers at the bottom and the left side.
11 x 53 x 916 x 13 x 1 x 55 = 381830020
Therefore, the lowest common multiple of 916,689,583,605 is 381830020.
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.
916 x 689 x 583 x 605 = 222606901660
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.
916 : 1, 2, 4, 229, 458, 916
689 : 1, 13, 53, 689
583 : 1, 11, 53, 583
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,689,583,605, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
689:13x 53
583:11x 53
605:5x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 53 = 583
Therefore, the value for common factors is 583.
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 = 222606901660/(1x583)
LCM = 222606901660/583
LCM = 381830020
Thus, we can understand that the LCM of 916,689,583,605 is 381830020.
