Given numbers are 721,757,757,419

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

The LCM of 721,757,757,419 is 228688943.

Find LCM of 721,757,757,419 with Prime Factorization

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

757 x 721 x 1 x 1 x 419 = 228688943

Therefore, the lowest common multiple of 721,757,757,419 is 228688943.

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.

721 x 757 x 757 x 419 = 173117529851

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.

721 : 1, 7, 103, 721

757 : 1, 757

757 : 1, 757

419 : 1, 419

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,757,757,419, is 1.

Now, the common factors can be found like this.

721:7x 103

757:757

757:757

419:419

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

757 = 757

Therefore, the value for common factors is 757.

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 = 173117529851/(1x757)

LCM = 173117529851/757

LCM = 228688943

Thus, we can understand that the LCM of 721,757,757,419 is 228688943.
