Given numbers are 909,685,424,572,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,685,424,572,856 is 4039616397960.
Find LCM of 909,685,424,572,856 with Prime Factorization
| 2 | 909, 685, 424, 572, 856 |
| 2 | 909, 685, 212, 286, 428 |
| 2 | 909, 685, 106, 143, 214 |
| 909, 685, 53, 143, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 909 x 685 x 53 x 143 x 107 = 4039616397960
Therefore, the lowest common multiple of 909,685,424,572,856 is 4039616397960.
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.
909 x 685 x 424 x 572 x 856 = 129267724734720
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.
909 : 1, 3, 9, 101, 303, 909
685 : 1, 5, 137, 685
424 : 1, 2, 4, 8, 53, 106, 212, 424
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,685,424,572,856, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
685:5x 137
424:2x 2x 2x 53
572:2x 2x 11x 13
856:2x 2x 2x 107
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 2 = 32
Therefore, the value for common factors is 32.
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 = 129267724734720/(1x32)
LCM = 129267724734720/32
LCM = 4039616397960
Thus, we can understand that the LCM of 909,685,424,572,856 is 4039616397960.
