Find LCM of 856,888,781,432,400 with Prime Factorization
| 2 | 856, 888, 781, 432, 400 |
| 2 | 428, 444, 781, 216, 200 |
| 2 | 214, 222, 781, 108, 100 |
| 2 | 107, 111, 781, 54, 50 |
| 3 | 107, 111, 781, 27, 25 |
| 107, 37, 781, 9, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 107 x 37 x 781 x 9 x 25 = 33393373200
Therefore, the lowest common multiple of 856,888,781,432,400 is 33393373200.
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.
856 x 888 x 781 x 432 x 400 = 102584442470400
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
781 : 1, 11, 71, 781
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,888,781,432,400, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
888:2x 2x 2x 3x 37
781:11x 71
432:2x 2x 2x 2x 3x 3x 3
400:2x 2x 2x 2x 5x 5
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 2x 2x 2x 2x 2x 2x 3 = 3072
Therefore, the value for common factors is 3072.
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 = 102584442470400/(1x3072)
LCM = 102584442470400/3072
LCM = 33393373200
Thus, we can understand that the LCM of 856,888,781,432,400 is 33393373200.
