The LCM of 738,121,663,638,908 is 259829140428.
Find LCM of 738,121,663,638,908 with Prime Factorization
2 | 738, 121, 663, 638, 908 |
3 | 369, 121, 663, 319, 454 |
11 | 123, 121, 221, 319, 454 |
123, 11, 221, 29, 454 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 123 x 11 x 221 x 29 x 454 = 259829140428
Therefore, the lowest common multiple of 738,121,663,638,908 is 259829140428.
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.
738 x 121 x 663 x 638 x 908 = 34297446536496
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.
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
121 : 1, 11, 121
663 : 1, 3, 13, 17, 39, 51, 221, 663
638 : 1, 2, 11, 22, 29, 58, 319, 638
908 : 1, 2, 4, 227, 454, 908
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,121,663,638,908, is 1.
Now, the common factors can be found like this.
738:2x 3x 3x 41
121:11x 11
663:3x 13x 17
638:2x 11x 29
908:2x 2x 227
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 11 = 132
Therefore, the value for common factors is 132.
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 = 34297446536496/(1x132)
LCM = 34297446536496/132
LCM = 259829140428
Thus, we can understand that the LCM of 738,121,663,638,908 is 259829140428.
