Given numbers are 991,974,709,487

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

The LCM of 991,974,709,487 is 684350906.

Find LCM of 991,974,709,487 with Prime Factorization

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

487 x 991 x 2 x 709 x 1 = 684350906

Therefore, the lowest common multiple of 991,974,709,487 is 684350906.

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 974 x 709 x 487 = 333278891222

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

974 : 1, 2, 487, 974

709 : 1, 709

487 : 1, 487

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,974,709,487, is 1.

Now, the common factors can be found like this.

991:991

974:2x 487

709:709

487:487

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

487 = 487

Therefore, the value for common factors is 487.

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 = 333278891222/(1x487)

LCM = 333278891222/487

LCM = 684350906

Thus, we can understand that the LCM of 991,974,709,487 is 684350906.
