Given numbers are 133,731,731,821

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

The LCM of 133,731,731,821 is 79820083.

Find LCM of 133,731,731,821 with Prime Factorization

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

17 x 43 x 133 x 1 x 1 x 821 = 79820083

Therefore, the lowest common multiple of 133,731,731,821 is 79820083.

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.

133 x 731 x 731 x 821 = 58348480673

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.

133 : 1, 7, 19, 133

731 : 1, 17, 43, 731

731 : 1, 17, 43, 731

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 133,731,731,821, is 1.

Now, the common factors can be found like this.

133:7x 19

731:17x 43

731:17x 43

821:821

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

17x 43 = 731

Therefore, the value for common factors is 731.

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 = 58348480673/(1x731)

LCM = 58348480673/731

LCM = 79820083

Thus, we can understand that the LCM of 133,731,731,821 is 79820083.
