The LCM of 931,570,435,906 is 122305470.
Find LCM of 931,570,435,906 with Prime Factorization
| 2 | 931, 570, 435, 906 |
| 3 | 931, 285, 435, 453 |
| 5 | 931, 95, 145, 151 |
| 19 | 931, 19, 29, 151 |
| 49, 1, 29, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 49 x 1 x 29 x 151 = 122305470
Therefore, the lowest common multiple of 931,570,435,906 is 122305470.
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.
931 x 570 x 435 x 906 = 209142353700
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.
931 : 1, 7, 19, 49, 133, 931
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
435 : 1, 3, 5, 15, 29, 87, 145, 435
906 : 1, 2, 3, 6, 151, 302, 453, 906
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,570,435,906, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
570:2x 3x 5x 19
435:3x 5x 29
906:2x 3x 151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 19 = 1710
Therefore, the value for common factors is 1710.
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 = 209142353700/(1x1710)
LCM = 209142353700/1710
LCM = 122305470
Thus, we can understand that the LCM of 931,570,435,906 is 122305470.
