Find LCM of 816,968,154,561,722 with Prime Factorization
| 2 | 816, 968, 154, 561, 722 |
| 2 | 408, 484, 77, 561, 361 |
| 2 | 204, 242, 77, 561, 361 |
| 3 | 102, 121, 77, 561, 361 |
| 11 | 34, 121, 77, 187, 361 |
| 17 | 34, 11, 7, 17, 361 |
| 2, 11, 7, 1, 361 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 17 x 2 x 11 x 7 x 1 x 361 = 249505872
Therefore, the lowest common multiple of 816,968,154,561,722 is 249505872.
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.
816 x 968 x 154 x 561 x 722 = 49270423555584
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
154 : 1, 2, 7, 11, 14, 22, 77, 154
561 : 1, 3, 11, 17, 33, 51, 187, 561
722 : 1, 2, 19, 38, 361, 722
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,968,154,561,722, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
968:2x 2x 2x 11x 11
154:2x 7x 11
561:3x 11x 17
722:2x 19x 19
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 3x 11x 11x 17 = 197472
Therefore, the value for common factors is 197472.
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 = 49270423555584/(1x197472)
LCM = 49270423555584/197472
LCM = 249505872
Thus, we can understand that the LCM of 816,968,154,561,722 is 249505872.
