Given numbers are 991,706,991,905

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

The LCM of 991,706,991,905 is 633179630.

Find LCM of 991,706,991,905 with Prime Factorization

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

991 x 1 x 706 x 1 x 905 = 633179630

Therefore, the lowest common multiple of 991,706,991,905 is 633179630.

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.

991 x 706 x 991 x 905 = 627481013330

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.

991 : 1, 991

706 : 1, 2, 353, 706

991 : 1, 991

905 : 1, 5, 181, 905

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,706,991,905, is 1.

Now, the common factors can be found like this.

991:991

706:2x 353

991:991

905:5x 181

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 = 627481013330/(1x991)

LCM = 627481013330/991

LCM = 633179630

Thus, we can understand that the LCM of 991,706,991,905 is 633179630.
