Find LCM of 906,945,702,385 with Prime Factorization
| 2 | 906, 945, 702, 385 |
| 3 | 453, 945, 351, 385 |
| 3 | 151, 315, 117, 385 |
| 3 | 151, 105, 39, 385 |
| 5 | 151, 35, 13, 385 |
| 7 | 151, 7, 13, 77 |
| 151, 1, 13, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 7 x 151 x 1 x 13 x 11 = 40810770
Therefore, the lowest common multiple of 906,945,702,385 is 40810770.
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 945 x 702 x 385 = 231397065900
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
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,945,702,385, is 1.
Now, the common factors can be found like this.
906:2x 3x 151
945:3x 3x 3x 5x 7
702:2x 3x 3x 3x 13
385:5x 7x 11
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 3x 3x 5x 7 = 5670
Therefore, the value for common factors is 5670.
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 = 231397065900/(1x5670)
LCM = 231397065900/5670
LCM = 40810770
Thus, we can understand that the LCM of 906,945,702,385 is 40810770.
