Find LCM of 468,117,786,655,715 with Prime Factorization
| 2 | 468, 117, 786, 655, 715 |
| 3 | 234, 117, 393, 655, 715 |
| 3 | 78, 39, 131, 655, 715 |
| 5 | 26, 13, 131, 655, 715 |
| 13 | 26, 13, 131, 131, 143 |
| 131 | 2, 1, 131, 131, 11 |
| 2, 1, 1, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 13 x 131 x 2 x 1 x 1 x 1 x 11 = 3371940
Therefore, the lowest common multiple of 468,117,786,655,715 is 3371940.
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.
468 x 117 x 786 x 655 x 715 = 20155872508200
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.
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
117 : 1, 3, 9, 13, 39, 117
786 : 1, 2, 3, 6, 131, 262, 393, 786
655 : 1, 5, 131, 655
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,117,786,655,715, is 1.
Now, the common factors can be found like this.
468:2x 2x 3x 3x 13
117:3x 3x 13
786:2x 3x 131
655:5x 131
715:5x 11x 13
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 3x 3x 5x 13x 13x 131 = 5977530
Therefore, the value for common factors is 5977530.
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 = 20155872508200/(1x5977530)
LCM = 20155872508200/5977530
LCM = 3371940
Thus, we can understand that the LCM of 468,117,786,655,715 is 3371940.
