Given numbers are 9,722,791,399
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 9,722,791,399 is 5139918.
Find LCM of 9,722,791,399 with Prime Factorization
| 3 | 9, 722, 791, 399 |
| 7 | 3, 722, 791, 133 |
| 19 | 3, 722, 113, 19 |
| 3, 38, 113, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 19 x 3 x 38 x 113 x 1 = 5139918
Therefore, the lowest common multiple of 9,722,791,399 is 5139918.
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.
9 x 722 x 791 x 399 = 2050827282
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.
9 : 1, 3, 9
722 : 1, 2, 19, 38, 361, 722
791 : 1, 7, 113, 791
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 9,722,791,399, is 1.
Now, the common factors can be found like this.
9:3x 3
722:2x 19x 19
791:7x 113
399:3x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 19 = 399
Therefore, the value for common factors is 399.
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 = 2050827282/(1x399)
LCM = 2050827282/399
LCM = 5139918
Thus, we can understand that the LCM of 9,722,791,399 is 5139918.
