Find LCM of 615,912,152,957,899 with Prime Factorization
| 2 | 615, 912, 152, 957, 899 |
| 2 | 615, 456, 76, 957, 899 |
| 2 | 615, 228, 38, 957, 899 |
| 3 | 615, 114, 19, 957, 899 |
| 19 | 205, 38, 19, 319, 899 |
| 29 | 205, 2, 1, 319, 899 |
| 205, 2, 1, 11, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 19 x 29 x 205 x 2 x 1 x 11 x 31 = 1848847440
Therefore, the lowest common multiple of 615,912,152,957,899 is 1848847440.
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 912 x 152 x 957 x 899 = 73347475639680
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
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
152 : 1, 2, 4, 8, 19, 38, 76, 152
957 : 1, 3, 11, 29, 33, 87, 319, 957
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,912,152,957,899, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
912:2x 2x 2x 2x 3x 19
152:2x 2x 2x 19
957:3x 11x 29
899:29x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3x 19x 29 = 39672
Therefore, the value for common factors is 39672.
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 = 73347475639680/(1x39672)
LCM = 73347475639680/39672
LCM = 1848847440
Thus, we can understand that the LCM of 615,912,152,957,899 is 1848847440.
