Given numbers are 7,430,991,991

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

The LCM of 7,430,991,991 is 2982910.

Find LCM of 7,430,991,991 with Prime Factorization

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

991 x 7 x 430 x 1 x 1 = 2982910

Therefore, the lowest common multiple of 7,430,991,991 is 2982910.

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 430 x 991 x 991 = 2956063810

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

430 : 1, 2, 5, 10, 43, 86, 215, 430

991 : 1, 991

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,430,991,991, is 1.

Now, the common factors can be found like this.

7:7

430:2x 5x 43

991:991

991:991

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

991 = 991

Therefore, the value for common factors is 991.

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 = 2956063810/(1x991)

LCM = 2956063810/991

LCM = 2982910

Thus, we can understand that the LCM of 7,430,991,991 is 2982910.

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

• LCM of 5, 238, 318, 555
