Given numbers are 986,873,690,631
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 986,873,690,631 is 62462355570.
Find LCM of 986,873,690,631 with Prime Factorization
| 2 | 986, 873, 690, 631 |
| 3 | 493, 873, 345, 631 |
| 493, 291, 115, 631 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 493 x 291 x 115 x 631 = 62462355570
Therefore, the lowest common multiple of 986,873,690,631 is 62462355570.
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.
986 x 873 x 690 x 631 = 374774133420
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
873 : 1, 3, 9, 97, 291, 873
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
631 : 1, 631
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,873,690,631, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
873:3x 3x 97
690:2x 3x 5x 23
631:631
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 374774133420/(1x6)
LCM = 374774133420/6
LCM = 62462355570
Thus, we can understand that the LCM of 986,873,690,631 is 62462355570.
