Given numbers are 128,265,712,814,785
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 128,265,712,814,785 is 192903413120.
Find LCM of 128,265,712,814,785 with Prime Factorization
| 2 | 128, 265, 712, 814, 785 |
| 2 | 64, 265, 356, 407, 785 |
| 2 | 32, 265, 178, 407, 785 |
| 5 | 16, 265, 89, 407, 785 |
| 16, 53, 89, 407, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 16 x 53 x 89 x 407 x 157 = 192903413120
Therefore, the lowest common multiple of 128,265,712,814,785 is 192903413120.
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 265 x 712 x 814 x 785 = 15432273049600
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
265 : 1, 5, 53, 265
712 : 1, 2, 4, 8, 89, 178, 356, 712
814 : 1, 2, 11, 22, 37, 74, 407, 814
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,265,712,814,785, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
265:5x 53
712:2x 2x 2x 89
814:2x 11x 37
785:5x 157
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 5 = 80
Therefore, the value for common factors is 80.
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 = 15432273049600/(1x80)
LCM = 15432273049600/80
LCM = 192903413120
Thus, we can understand that the LCM of 128,265,712,814,785 is 192903413120.
