Given numbers are 7,971,971,218

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

The LCM of 7,971,971,218 is 1481746.

Find LCM of 7,971,971,218 with Prime Factorization

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

971 x 7 x 1 x 1 x 218 = 1481746

Therefore, the lowest common multiple of 7,971,971,218 is 1481746.

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.

7 x 971 x 971 x 218 = 1438775366

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.

7 : 1, 7

971 : 1, 971

971 : 1, 971

218 : 1, 2, 109, 218

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,971,971,218, is 1.

Now, the common factors can be found like this.

7:7

971:971

971:971

218:2x 109

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

971 = 971

Therefore, the value for common factors is 971.

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 = 1438775366/(1x971)

LCM = 1438775366/971

LCM = 1481746

Thus, we can understand that the LCM of 7,971,971,218 is 1481746.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 1, 648, 388, 697
