Given numbers are 634,309,591,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 634,309,591,154 is 2971698114.
Find LCM of 634,309,591,154 with Prime Factorization
| 2 | 634, 309, 591, 154 |
| 3 | 317, 309, 591, 77 |
| 317, 103, 197, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 317 x 103 x 197 x 77 = 2971698114
Therefore, the lowest common multiple of 634,309,591,154 is 2971698114.
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 309 x 591 x 154 = 17830188684
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
309 : 1, 3, 103, 309
591 : 1, 3, 197, 591
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,309,591,154, is 1.
Now, the common factors can be found like this.
634:2x 317
309:3x 103
591:3x 197
154:2x 7x 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 = 17830188684/(1x6)
LCM = 17830188684/6
LCM = 2971698114
Thus, we can understand that the LCM of 634,309,591,154 is 2971698114.
