Given numbers are 722,763,969,307,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,763,969,307,990 is 1423161646830.
Find LCM of 722,763,969,307,990 with Prime Factorization
| 2 | 722, 763, 969, 307, 990 |
| 3 | 361, 763, 969, 307, 495 |
| 19 | 361, 763, 323, 307, 165 |
| 19, 763, 17, 307, 165 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 19 x 763 x 17 x 307 x 165 = 1423161646830
Therefore, the lowest common multiple of 722,763,969,307,990 is 1423161646830.
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.
722 x 763 x 969 x 307 x 990 = 162240427738620
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.
722 : 1, 2, 19, 38, 361, 722
763 : 1, 7, 109, 763
969 : 1, 3, 17, 19, 51, 57, 323, 969
307 : 1, 307
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,763,969,307,990, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
763:7x 109
969:3x 17x 19
307:307
990:2x 3x 3x 5x 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 3x 19 = 114
Therefore, the value for common factors is 114.
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 = 162240427738620/(1x114)
LCM = 162240427738620/114
LCM = 1423161646830
Thus, we can understand that the LCM of 722,763,969,307,990 is 1423161646830.
