Find LCM of 231,698,992,352 with Prime Factorization
| 2 | 231, 698, 992, 352 |
| 2 | 231, 349, 496, 176 |
| 2 | 231, 349, 248, 88 |
| 2 | 231, 349, 124, 44 |
| 2 | 231, 349, 62, 22 |
| 11 | 231, 349, 31, 11 |
| 21, 349, 31, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 11 x 21 x 349 x 31 x 1 = 79974048
Therefore, the lowest common multiple of 231,698,992,352 is 79974048.
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.
231 x 698 x 992 x 352 = 56301729792
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
698 : 1, 2, 349, 698
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,698,992,352, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
698:2x 349
992:2x 2x 2x 2x 2x 31
352:2x 2x 2x 2x 2x 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 2x 2x 11 = 704
Therefore, the value for common factors is 704.
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 = 56301729792/(1x704)
LCM = 56301729792/704
LCM = 79974048
Thus, we can understand that the LCM of 231,698,992,352 is 79974048.
