Find LCM of 784,856,802,760,252 with Prime Factorization
| 2 | 784, 856, 802, 760, 252 |
| 2 | 392, 428, 401, 380, 126 |
| 2 | 196, 214, 401, 190, 63 |
| 7 | 98, 107, 401, 95, 63 |
| 14, 107, 401, 95, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 14 x 107 x 401 x 95 x 9 = 28761420240
Therefore, the lowest common multiple of 784,856,802,760,252 is 28761420240.
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.
784 x 856 x 802 x 760 x 252 = 103080930140160
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
856 : 1, 2, 4, 8, 107, 214, 428, 856
802 : 1, 2, 401, 802
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,856,802,760,252, is 2.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
856:2x 2x 2x 107
802:2x 401
760:2x 2x 2x 5x 19
252:2x 2x 3x 3x 7
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 7 = 1792
Therefore, the value for common factors is 1792.
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 = 103080930140160/(2x1792)
LCM = 103080930140160/3584
LCM = 28761420240
Thus, we can understand that the LCM of 784,856,802,760,252 is 28761420240.
