Given numbers are 127,821,663,821

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

The LCM of 127,821,663,821 is 69129021.

Find LCM of 127,821,663,821 with Prime Factorization

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

821 x 127 x 1 x 663 x 1 = 69129021

Therefore, the lowest common multiple of 127,821,663,821 is 69129021.

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.

127 x 821 x 663 x 821 = 56754926241

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.

127 : 1, 127

821 : 1, 821

663 : 1, 3, 13, 17, 39, 51, 221, 663

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 127,821,663,821, is 1.

Now, the common factors can be found like this.

127:127

821:821

663:3x 13x 17

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.

821 = 821

Therefore, the value for common factors is 821.

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 = 56754926241/(1x821)

LCM = 56754926241/821

LCM = 69129021

Thus, we can understand that the LCM of 127,821,663,821 is 69129021.
