Given numbers are 988,291,442,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 988,291,442,170 is 24438180.
Find LCM of 988,291,442,170 with Prime Factorization
| 2 | 988, 291, 442, 170 |
| 13 | 494, 291, 221, 85 |
| 17 | 38, 291, 17, 85 |
| 38, 291, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 38 x 291 x 1 x 5 = 24438180
Therefore, the lowest common multiple of 988,291,442,170 is 24438180.
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.
988 x 291 x 442 x 170 = 21603351120
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
291 : 1, 3, 97, 291
442 : 1, 2, 13, 17, 26, 34, 221, 442
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,291,442,170, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
291:3x 97
442:2x 13x 17
170:2x 5x 17
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 13x 17 = 884
Therefore, the value for common factors is 884.
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 = 21603351120/(1x884)
LCM = 21603351120/884
LCM = 24438180
Thus, we can understand that the LCM of 988,291,442,170 is 24438180.
