Given numbers are 905,535,691,691

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

The LCM of 905,535,691,691 is 66912985.

Find LCM of 905,535,691,691 with Prime Factorization

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

5 x 691 x 181 x 107 x 1 x 1 = 66912985

Therefore, the lowest common multiple of 905,535,691,691 is 66912985.

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.

905 x 535 x 691 x 691 = 231184363175

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.

905 : 1, 5, 181, 905

535 : 1, 5, 107, 535

691 : 1, 691

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,535,691,691, is 1.

Now, the common factors can be found like this.

905:5x 181

535:5x 107

691:691

691:691

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

5x 691 = 3455

Therefore, the value for common factors is 3455.

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 = 231184363175/(1x3455)

LCM = 231184363175/3455

LCM = 66912985

Thus, we can understand that the LCM of 905,535,691,691 is 66912985.
