Find LCM of 742,638,561,738,459 with Prime Factorization
| 2 | 742, 638, 561, 738, 459 |
| 3 | 371, 319, 561, 369, 459 |
| 3 | 371, 319, 187, 123, 153 |
| 11 | 371, 319, 187, 41, 51 |
| 17 | 371, 29, 17, 41, 51 |
| 371, 29, 1, 41, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 17 x 371 x 29 x 1 x 41 x 3 = 4454419662
Therefore, the lowest common multiple of 742,638,561,738,459 is 4454419662.
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 638 x 561 x 738 x 459 = 89961459493752
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
638 : 1, 2, 11, 22, 29, 58, 319, 638
561 : 1, 3, 11, 17, 33, 51, 187, 561
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
459 : 1, 3, 9, 17, 27, 51, 153, 459
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,638,561,738,459, is 1.
Now, the common factors can be found like this.
742:2x 7x 53
638:2x 11x 29
561:3x 11x 17
738:2x 3x 3x 41
459:3x 3x 3x 17
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 3x 3x 3x 11x 17 = 20196
Therefore, the value for common factors is 20196.
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 = 89961459493752/(1x20196)
LCM = 89961459493752/20196
LCM = 4454419662
Thus, we can understand that the LCM of 742,638,561,738,459 is 4454419662.
