Given numbers are 742,742,638,754
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 742,742,638,754 is 3077074.
Find LCM of 742,742,638,754 with Prime Factorization
| 2 | 742, 742, 638, 754 |
| 7 | 371, 371, 319, 377 |
| 29 | 53, 53, 319, 377 |
| 53 | 53, 53, 11, 13 |
| 1, 1, 11, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 29 x 53 x 1 x 1 x 11 x 13 = 3077074
Therefore, the lowest common multiple of 742,742,638,754 is 3077074.
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.
742 x 742 x 638 x 754 = 264849913328
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.
742 : 1, 2, 7, 14, 53, 106, 371, 742
742 : 1, 2, 7, 14, 53, 106, 371, 742
638 : 1, 2, 11, 22, 29, 58, 319, 638
754 : 1, 2, 13, 26, 29, 58, 377, 754
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,742,638,754, is 2.
Now, the common factors can be found like this.
742:2x 7x 53
742:2x 7x 53
638:2x 11x 29
754:2x 13x 29
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 7x 29x 53 = 43036
Therefore, the value for common factors is 43036.
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 = 264849913328/(2x43036)
LCM = 264849913328/86072
LCM = 3077074
Thus, we can understand that the LCM of 742,742,638,754 is 3077074.
