Find LCM of 104,744,781,786 with Prime Factorization
| 2 | 104, 744, 781, 786 |
| 2 | 52, 372, 781, 393 |
| 2 | 26, 186, 781, 393 |
| 3 | 13, 93, 781, 393 |
| 13, 31, 781, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 31 x 781 x 131 = 989551992
Therefore, the lowest common multiple of 104,744,781,786 is 989551992.
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.
104 x 744 x 781 x 786 = 47498495616
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.
104 : 1, 2, 4, 8, 13, 26, 52, 104
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
781 : 1, 11, 71, 781
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 104,744,781,786, is 1.
Now, the common factors can be found like this.
104:2x 2x 2x 13
744:2x 2x 2x 3x 31
781:11x 71
786:2x 3x 131
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 3 = 48
Therefore, the value for common factors is 48.
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 = 47498495616/(1x48)
LCM = 47498495616/48
LCM = 989551992
Thus, we can understand that the LCM of 104,744,781,786 is 989551992.
