Given numbers are 421,356,166,810

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

The LCM of 421,356,166,810 is 5038081740.

Find LCM of 421,356,166,810 with Prime Factorization

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

2 x 421 x 178 x 83 x 405 = 5038081740

Therefore, the lowest common multiple of 421,356,166,810 is 5038081740.

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.

421 x 356 x 166 x 810 = 20152326960

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.

421 : 1, 421

356 : 1, 2, 4, 89, 178, 356

166 : 1, 2, 83, 166

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,356,166,810, is 1.

Now, the common factors can be found like this.

421:421

356:2x 2x 89

166:2x 83

810:2x 3x 3x 3x 3x 5

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 20152326960/(1x4)

LCM = 20152326960/4

LCM = 5038081740

Thus, we can understand that the LCM of 421,356,166,810 is 5038081740.
