Find LCM of 257,736,992,915 with Prime Factorization
| 2 | 257, 736, 992, 915 |
| 2 | 257, 368, 496, 915 |
| 2 | 257, 184, 248, 915 |
| 2 | 257, 92, 124, 915 |
| 2 | 257, 46, 62, 915 |
| 257, 23, 31, 915 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 257 x 23 x 31 x 915 = 5365296480
Therefore, the lowest common multiple of 257,736,992,915 is 5365296480.
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.
257 x 736 x 992 x 915 = 171689487360
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.
257 : 1, 257
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,736,992,915, is 1.
Now, the common factors can be found like this.
257:257
736:2x 2x 2x 2x 2x 23
992:2x 2x 2x 2x 2x 31
915:3x 5x 61
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 2x 2 = 32
Therefore, the value for common factors is 32.
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 = 171689487360/(1x32)
LCM = 171689487360/32
LCM = 5365296480
Thus, we can understand that the LCM of 257,736,992,915 is 5365296480.
