Find LCM of 798,245,612,561,123 with Prime Factorization
| 2 | 798, 245, 612, 561, 123 |
| 3 | 399, 245, 306, 561, 123 |
| 7 | 133, 245, 102, 187, 41 |
| 17 | 19, 35, 102, 187, 41 |
| 19, 35, 6, 11, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 19 x 35 x 6 x 11 x 41 = 1284835860
Therefore, the lowest common multiple of 798,245,612,561,123 is 1284835860.
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.
798 x 245 x 612 x 561 x 123 = 8256355236360
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.
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
245 : 1, 5, 7, 35, 49, 245
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
561 : 1, 3, 11, 17, 33, 51, 187, 561
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,245,612,561,123, is 1.
Now, the common factors can be found like this.
798:2x 3x 7x 19
245:5x 7x 7
612:2x 2x 3x 3x 17
561:3x 11x 17
123:3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7x 17 = 6426
Therefore, the value for common factors is 6426.
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 = 8256355236360/(1x6426)
LCM = 8256355236360/6426
LCM = 1284835860
Thus, we can understand that the LCM of 798,245,612,561,123 is 1284835860.
