The LCM of 615,308,759,959 is 596862420.
Find LCM of 615,308,759,959 with Prime Factorization
| 3 | 615, 308, 759, 959 |
| 7 | 205, 308, 253, 959 |
| 11 | 205, 44, 253, 137 |
| 205, 4, 23, 137 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 205 x 4 x 23 x 137 = 596862420
Therefore, the lowest common multiple of 615,308,759,959 is 596862420.
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.
615 x 308 x 759 x 959 = 137875219020
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
759 : 1, 3, 11, 23, 33, 69, 253, 759
959 : 1, 7, 137, 959
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,308,759,959, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
308:2x 2x 7x 11
759:3x 11x 23
959:7x 137
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 = 137875219020/(1x231)
LCM = 137875219020/231
LCM = 596862420
Thus, we can understand that the LCM of 615,308,759,959 is 596862420.
