Given numbers are 797,770,559,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 797,770,559,742 is 18181793630.
Find LCM of 797,770,559,742 with Prime Factorization
| 2 | 797, 770, 559, 742 |
| 7 | 797, 385, 559, 371 |
| 797, 55, 559, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 797 x 55 x 559 x 53 = 18181793630
Therefore, the lowest common multiple of 797,770,559,742 is 18181793630.
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.
797 x 770 x 559 x 742 = 254545110820
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.
797 : 1, 797
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
559 : 1, 13, 43, 559
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 797,770,559,742, is 1.
Now, the common factors can be found like this.
797:797
770:2x 5x 7x 11
559:13x 43
742:2x 7x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 254545110820/(1x14)
LCM = 254545110820/14
LCM = 18181793630
Thus, we can understand that the LCM of 797,770,559,742 is 18181793630.
