The LCM of 399,647,693,649,325 is 163352764575.
Find LCM of 399,647,693,649,325 with Prime Factorization
| 3 | 399, 647, 693, 649, 325 |
| 7 | 133, 647, 231, 649, 325 |
| 11 | 19, 647, 33, 649, 325 |
| 19, 647, 3, 59, 325 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 19 x 647 x 3 x 59 x 325 = 163352764575
Therefore, the lowest common multiple of 399,647,693,649,325 is 163352764575.
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.
399 x 647 x 693 x 649 x 325 = 37734488616825
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
647 : 1, 647
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
649 : 1, 11, 59, 649
325 : 1, 5, 13, 25, 65, 325
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,647,693,649,325, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
647:647
693:3x 3x 7x 11
649:11x 59
325:5x 5x 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 7x 11 = 231
Therefore, the value for common factors is 231.
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 = 37734488616825/(1x231)
LCM = 37734488616825/231
LCM = 163352764575
Thus, we can understand that the LCM of 399,647,693,649,325 is 163352764575.
