Given numbers are 185,319,639,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 185,319,639,639 is 37710585.
Find LCM of 185,319,639,639 with Prime Factorization
| 3 | 185, 319, 639, 639 |
| 3 | 185, 319, 213, 213 |
| 71 | 185, 319, 71, 71 |
| 185, 319, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 71 x 185 x 319 x 1 x 1 = 37710585
Therefore, the lowest common multiple of 185,319,639,639 is 37710585.
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.
185 x 319 x 639 x 639 = 24097063815
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.
185 : 1, 5, 37, 185
319 : 1, 11, 29, 319
639 : 1, 3, 9, 71, 213, 639
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 185,319,639,639, is 1.
Now, the common factors can be found like this.
185:5x 37
319:11x 29
639:3x 3x 71
639:3x 3x 71
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 71 = 639
Therefore, the value for common factors is 639.
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 = 24097063815/(1x639)
LCM = 24097063815/639
LCM = 37710585
Thus, we can understand that the LCM of 185,319,639,639 is 37710585.
