Given numbers are 128,304,989,950
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 128,304,989,950 is 60131200.
Find LCM of 128,304,989,950 with Prime Factorization
| 2 | 128, 304, 989, 950 |
| 2 | 64, 152, 989, 475 |
| 2 | 32, 76, 989, 475 |
| 2 | 16, 38, 989, 475 |
| 19 | 8, 19, 989, 475 |
| 8, 1, 989, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 19 x 8 x 1 x 989 x 25 = 60131200
Therefore, the lowest common multiple of 128,304,989,950 is 60131200.
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.
128 x 304 x 989 x 950 = 36559769600
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
989 : 1, 23, 43, 989
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,304,989,950, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
304:2x 2x 2x 2x 19
989:23x 43
950:2x 5x 5x 19
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 2x 2x 2x 19 = 608
Therefore, the value for common factors is 608.
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 = 36559769600/(1x608)
LCM = 36559769600/608
LCM = 60131200
Thus, we can understand that the LCM of 128,304,989,950 is 60131200.
