Given numbers are 903,197,197,989

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 903,197,197,989 is 4091493.

Find LCM of 903,197,197,989 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

43 x 197 x 21 x 1 x 1 x 23 = 4091493

Therefore, the lowest common multiple of 903,197,197,989 is 4091493.

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.

903 x 197 x 197 x 989 = 34659037203

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.

903 : 1, 3, 7, 21, 43, 129, 301, 903

197 : 1, 197

197 : 1, 197

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,197,197,989, is 1.

Now, the common factors can be found like this.

903:3x 7x 43

197:197

197:197

989:23x 43

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

43x 197 = 8471

Therefore, the value for common factors is 8471.

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 = 34659037203/(1x8471)

LCM = 34659037203/8471

LCM = 4091493

Thus, we can understand that the LCM of 903,197,197,989 is 4091493.
