Find LCM of 231,255,856,500,781 with Prime Factorization
| 2 | 231, 255, 856, 500, 781 |
| 2 | 231, 255, 428, 250, 781 |
| 3 | 231, 255, 214, 125, 781 |
| 5 | 77, 85, 214, 125, 781 |
| 11 | 77, 17, 214, 25, 781 |
| 7, 17, 214, 25, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 7 x 17 x 214 x 25 x 71 = 29833419000
Therefore, the lowest common multiple of 231,255,856,500,781 is 29833419000.
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.
231 x 255 x 856 x 500 x 781 = 19690056540000
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
255 : 1, 3, 5, 15, 17, 51, 85, 255
856 : 1, 2, 4, 8, 107, 214, 428, 856
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,255,856,500,781, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
255:3x 5x 17
856:2x 2x 2x 107
500:2x 2x 5x 5x 5
781:11x 71
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 3x 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 19690056540000/(1x660)
LCM = 19690056540000/660
LCM = 29833419000
Thus, we can understand that the LCM of 231,255,856,500,781 is 29833419000.
