Find LCM of 538,616,352,121 with Prime Factorization
| 2 | 538, 616, 352, 121 |
| 2 | 269, 308, 176, 121 |
| 2 | 269, 154, 88, 121 |
| 11 | 269, 77, 44, 121 |
| 269, 7, 4, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 269 x 7 x 4 x 11 = 7290976
Therefore, the lowest common multiple of 538,616,352,121 is 7290976.
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.
538 x 616 x 352 x 121 = 14115329536
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.
538 : 1, 2, 269, 538
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,616,352,121, is 1.
Now, the common factors can be found like this.
538:2x 269
616:2x 2x 2x 7x 11
352:2x 2x 2x 2x 2x 11
121:11x 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 2x 11x 11 = 1936
Therefore, the value for common factors is 1936.
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 = 14115329536/(1x1936)
LCM = 14115329536/1936
LCM = 7290976
Thus, we can understand that the LCM of 538,616,352,121 is 7290976.
