Given numbers are 646,622,873,491
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,622,873,491 is 86116950558.
Find LCM of 646,622,873,491 with Prime Factorization
| 2 | 646, 622, 873, 491 |
| 323, 311, 873, 491 |
Multiply the prime numbers at the bottom and the left side.
2 x 323 x 311 x 873 x 491 = 86116950558
Therefore, the lowest common multiple of 646,622,873,491 is 86116950558.
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.
646 x 622 x 873 x 491 = 172233901116
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
622 : 1, 2, 311, 622
873 : 1, 3, 9, 97, 291, 873
491 : 1, 491
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,622,873,491, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
622:2x 311
873:3x 3x 97
491:491
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 172233901116/(1x2)
LCM = 172233901116/2
LCM = 86116950558
Thus, we can understand that the LCM of 646,622,873,491 is 86116950558.
