Given numbers are 397,705,397,583,615
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,705,397,583,615 is 6690091155.
Find LCM of 397,705,397,583,615 with Prime Factorization
3 | 397, 705, 397, 583, 615 |
5 | 397, 235, 397, 583, 205 |
397 | 397, 47, 397, 583, 41 |
1, 47, 1, 583, 41 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 397 x 1 x 47 x 1 x 583 x 41 = 6690091155
Therefore, the lowest common multiple of 397,705,397,583,615 is 6690091155.
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 705 x 397 x 583 x 615 = 39839492828025
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
705 : 1, 3, 5, 15, 47, 141, 235, 705
397 : 1, 397
583 : 1, 11, 53, 583
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,705,397,583,615, is 1.
Now, the common factors can be found like this.
397:397
705:3x 5x 47
397:397
583:11x 53
615:3x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 397 = 5955
Therefore, the value for common factors is 5955.
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 = 39839492828025/(1x5955)
LCM = 39839492828025/5955
LCM = 6690091155
Thus, we can understand that the LCM of 397,705,397,583,615 is 6690091155.
