Given numbers are 428,102,411,703,417
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,102,411,703,417 is 292216434612.
Find LCM of 428,102,411,703,417 with Prime Factorization
| 2 | 428, 102, 411, 703, 417 |
| 3 | 214, 51, 411, 703, 417 |
| 214, 17, 137, 703, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 214 x 17 x 137 x 703 x 139 = 292216434612
Therefore, the lowest common multiple of 428,102,411,703,417 is 292216434612.
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.
428 x 102 x 411 x 703 x 417 = 5259895823016
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.
428 : 1, 2, 4, 107, 214, 428
102 : 1, 2, 3, 6, 17, 34, 51, 102
411 : 1, 3, 137, 411
703 : 1, 19, 37, 703
417 : 1, 3, 139, 417
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,102,411,703,417, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
102:2x 3x 17
411:3x 137
703:19x 37
417:3x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 5259895823016/(1x18)
LCM = 5259895823016/18
LCM = 292216434612
Thus, we can understand that the LCM of 428,102,411,703,417 is 292216434612.
