Given numbers are 322,988,646,979,697
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 322,988,646,979,697 is 108542117684.
Find LCM of 322,988,646,979,697 with Prime Factorization
| 2 | 322, 988, 646, 979, 697 |
| 17 | 161, 494, 323, 979, 697 |
| 19 | 161, 494, 19, 979, 41 |
| 161, 26, 1, 979, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 161 x 26 x 1 x 979 x 41 = 108542117684
Therefore, the lowest common multiple of 322,988,646,979,697 is 108542117684.
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.
322 x 988 x 646 x 979 x 697 = 140236416047728
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.
322 : 1, 2, 7, 14, 23, 46, 161, 322
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
646 : 1, 2, 17, 19, 34, 38, 323, 646
979 : 1, 11, 89, 979
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 322,988,646,979,697, is 1.
Now, the common factors can be found like this.
322:2x 7x 23
988:2x 2x 13x 19
646:2x 17x 19
979:11x 89
697:17x 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 2x 17x 19 = 1292
Therefore, the value for common factors is 1292.
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 = 140236416047728/(1x1292)
LCM = 140236416047728/1292
LCM = 108542117684
Thus, we can understand that the LCM of 322,988,646,979,697 is 108542117684.
