Given numbers are 971,763,436,721

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

The LCM of 971,763,436,721 is 305239676.

Find LCM of 971,763,436,721 with Prime Factorization

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

7 x 109 x 971 x 1 x 4 x 103 = 305239676

Therefore, the lowest common multiple of 971,763,436,721 is 305239676.

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.

971 x 763 x 436 x 721 = 232897872788

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.

971 : 1, 971

763 : 1, 7, 109, 763

436 : 1, 2, 4, 109, 218, 436

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,763,436,721, is 1.

Now, the common factors can be found like this.

971:971

763:7x 109

436:2x 2x 109

721:7x 103

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

7x 109 = 763

Therefore, the value for common factors is 763.

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 = 232897872788/(1x763)

LCM = 232897872788/763

LCM = 305239676

Thus, we can understand that the LCM of 971,763,436,721 is 305239676.
