Find LCM of 731,252,442,682,770 with Prime Factorization
| 2 | 731, 252, 442, 682, 770 |
| 7 | 731, 126, 221, 341, 385 |
| 11 | 731, 18, 221, 341, 55 |
| 17 | 731, 18, 221, 31, 5 |
| 43, 18, 13, 31, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 17 x 43 x 18 x 13 x 31 x 5 = 4083058980
Therefore, the lowest common multiple of 731,252,442,682,770 is 4083058980.
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.
731 x 252 x 442 x 682 x 770 = 42757793638560
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.
731 : 1, 17, 43, 731
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
442 : 1, 2, 13, 17, 26, 34, 221, 442
682 : 1, 2, 11, 22, 31, 62, 341, 682
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,252,442,682,770, is 1.
Now, the common factors can be found like this.
731:17x 43
252:2x 2x 3x 3x 7
442:2x 13x 17
682:2x 11x 31
770:2x 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 2x 2x 7x 11x 17 = 10472
Therefore, the value for common factors is 10472.
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 = 42757793638560/(1x10472)
LCM = 42757793638560/10472
LCM = 4083058980
Thus, we can understand that the LCM of 731,252,442,682,770 is 4083058980.
