Find LCM of 108,748,868,561 with Prime Factorization
| 2 | 108, 748, 868, 561 |
| 2 | 54, 374, 434, 561 |
| 3 | 27, 187, 217, 561 |
| 11 | 9, 187, 217, 187 |
| 17 | 9, 17, 217, 17 |
| 9, 1, 217, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 17 x 9 x 1 x 217 x 1 = 4382532
Therefore, the lowest common multiple of 108,748,868,561 is 4382532.
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.
108 x 748 x 868 x 561 = 39337607232
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.
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 108,748,868,561, is 1.
Now, the common factors can be found like this.
108:2x 2x 3x 3x 3
748:2x 2x 11x 17
868:2x 2x 7x 31
561:3x 11x 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 2x 2x 3x 11x 17 = 8976
Therefore, the value for common factors is 8976.
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 = 39337607232/(1x8976)
LCM = 39337607232/8976
LCM = 4382532
Thus, we can understand that the LCM of 108,748,868,561 is 4382532.
