The LCM of 906,693,782,126 is 81830826.
Find LCM of 906,693,782,126 with Prime Factorization
| 2 | 906, 693, 782, 126 |
| 3 | 453, 693, 391, 63 |
| 3 | 151, 231, 391, 21 |
| 7 | 151, 77, 391, 7 |
| 151, 11, 391, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 151 x 11 x 391 x 1 = 81830826
Therefore, the lowest common multiple of 906,693,782,126 is 81830826.
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.
906 x 693 x 782 x 126 = 61864104456
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.
906 : 1, 2, 3, 6, 151, 302, 453, 906
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
782 : 1, 2, 17, 23, 34, 46, 391, 782
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,693,782,126, is 1.
Now, the common factors can be found like this.
906:2x 3x 151
693:3x 3x 7x 11
782:2x 17x 23
126:2x 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 3x 3x 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 61864104456/(1x756)
LCM = 61864104456/756
LCM = 81830826
Thus, we can understand that the LCM of 906,693,782,126 is 81830826.
