Given numbers are 417,393,671,869
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 417,393,671,869 is 2895722643.
Find LCM of 417,393,671,869 with Prime Factorization
| 3 | 417, 393, 671, 869 |
| 11 | 139, 131, 671, 869 |
| 139, 131, 61, 79 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 139 x 131 x 61 x 79 = 2895722643
Therefore, the lowest common multiple of 417,393,671,869 is 2895722643.
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.
417 x 393 x 671 x 869 = 95558847219
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.
417 : 1, 3, 139, 417
393 : 1, 3, 131, 393
671 : 1, 11, 61, 671
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,393,671,869, is 1.
Now, the common factors can be found like this.
417:3x 139
393:3x 131
671:11x 61
869:11x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 95558847219/(1x33)
LCM = 95558847219/33
LCM = 2895722643
Thus, we can understand that the LCM of 417,393,671,869 is 2895722643.
