Given numbers are 398,802,615,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,802,615,121 is 11876485170.
Find LCM of 398,802,615,121 with Prime Factorization
2 | 398, 802, 615, 121 |
199, 401, 615, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 199 x 401 x 615 x 121 = 11876485170
Therefore, the lowest common multiple of 398,802,615,121 is 11876485170.
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.
398 x 802 x 615 x 121 = 23752970340
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.
398 : 1, 2, 199, 398
802 : 1, 2, 401, 802
615 : 1, 3, 5, 15, 41, 123, 205, 615
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,802,615,121, is 1.
Now, the common factors can be found like this.
398:2x 199
802:2x 401
615:3x 5x 41
121:11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 23752970340/(1x2)
LCM = 23752970340/2
LCM = 11876485170
Thus, we can understand that the LCM of 398,802,615,121 is 11876485170.
