The LCM of 517,715,141,117 is 302445.
Find LCM of 517,715,141,117 with Prime Factorization
| 3 | 517, 715, 141, 117 |
| 11 | 517, 715, 47, 39 |
| 13 | 47, 65, 47, 39 |
| 47 | 47, 5, 47, 3 |
| 1, 5, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 13 x 47 x 1 x 5 x 1 x 3 = 302445
Therefore, the lowest common multiple of 517,715,141,117 is 302445.
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.
517 x 715 x 141 x 117 = 6098198535
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.
517 : 1, 11, 47, 517
715 : 1, 5, 11, 13, 55, 65, 143, 715
141 : 1, 3, 47, 141
117 : 1, 3, 9, 13, 39, 117
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,715,141,117, is 1.
Now, the common factors can be found like this.
517:11x 47
715:5x 11x 13
141:3x 47
117:3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 13x 47 = 20163
Therefore, the value for common factors is 20163.
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 = 6098198535/(1x20163)
LCM = 6098198535/20163
LCM = 302445
Thus, we can understand that the LCM of 517,715,141,117 is 302445.
