Given numbers are 682,575,991,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 682,575,991,391 is 6606551050.
Find LCM of 682,575,991,391 with Prime Factorization
23 | 682, 575, 991, 391 |
682, 25, 991, 17 |
Multiply the prime numbers at the bottom and the left side.
23 x 682 x 25 x 991 x 17 = 6606551050
Therefore, the lowest common multiple of 682,575,991,391 is 6606551050.
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.
682 x 575 x 991 x 391 = 151950674150
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
575 : 1, 5, 23, 25, 115, 575
991 : 1, 991
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,575,991,391, is 1.
Now, the common factors can be found like this.
682:2x 11x 31
575:5x 5x 23
991:991
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 151950674150/(1x23)
LCM = 151950674150/23
LCM = 6606551050
Thus, we can understand that the LCM of 682,575,991,391 is 6606551050.
