Given numbers are 397,861,682,659,397
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,861,682,659,397 is 153625548846.
Find LCM of 397,861,682,659,397 with Prime Factorization
397 | 397, 861, 682, 659, 397 |
1, 861, 682, 659, 1 |
Multiply the prime numbers at the bottom and the left side.
397 x 1 x 861 x 682 x 659 x 1 = 153625548846
Therefore, the lowest common multiple of 397,861,682,659,397 is 153625548846.
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.
397 x 861 x 682 x 659 x 397 = 60989342891862
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.
397 : 1, 397
861 : 1, 3, 7, 21, 41, 123, 287, 861
682 : 1, 2, 11, 22, 31, 62, 341, 682
659 : 1, 659
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,861,682,659,397, is 1.
Now, the common factors can be found like this.
397:397
861:3x 7x 41
682:2x 11x 31
659:659
397:397
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
397 = 397
Therefore, the value for common factors is 397.
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 = 60989342891862/(1x397)
LCM = 60989342891862/397
LCM = 153625548846
Thus, we can understand that the LCM of 397,861,682,659,397 is 153625548846.
