Given numbers are 657,717,731,534

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

The LCM of 657,717,731,534 is 20431518714.

Find LCM of 657,717,731,534 with Prime Factorization

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

3 x 219 x 239 x 731 x 178 = 20431518714

Therefore, the lowest common multiple of 657,717,731,534 is 20431518714.

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.

657 x 717 x 731 x 534 = 183883668426

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.

657 : 1, 3, 9, 73, 219, 657

717 : 1, 3, 239, 717

731 : 1, 17, 43, 731

534 : 1, 2, 3, 6, 89, 178, 267, 534

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,717,731,534, is 1.

Now, the common factors can be found like this.

657:3x 3x 73

717:3x 239

731:17x 43

534:2x 3x 89

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 183883668426/(1x9)

LCM = 183883668426/9

LCM = 20431518714

Thus, we can understand that the LCM of 657,717,731,534 is 20431518714.
