Find LCM of 317,846,423,461,991 with Prime Factorization
| 3 | 317, 846, 423, 461, 991 |
| 3 | 317, 282, 141, 461, 991 |
| 47 | 317, 94, 47, 461, 991 |
| 317, 2, 1, 461, 991 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 47 x 317 x 2 x 1 x 461 x 991 = 122519214882
Therefore, the lowest common multiple of 317,846,423,461,991 is 122519214882.
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.
317 x 846 x 423 x 461 x 991 = 51825627895086
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.
317 : 1, 317
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
423 : 1, 3, 9, 47, 141, 423
461 : 1, 461
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 317,846,423,461,991, is 1.
Now, the common factors can be found like this.
317:317
846:2x 3x 3x 47
423:3x 3x 47
461:461
991:991
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 47 = 423
Therefore, the value for common factors is 423.
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 = 51825627895086/(1x423)
LCM = 51825627895086/423
LCM = 122519214882
Thus, we can understand that the LCM of 317,846,423,461,991 is 122519214882.
