Given numbers are 431,214,621,161

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

The LCM of 431,214,621,161 is 400941198.

Find LCM of 431,214,621,161 with Prime Factorization

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

23 x 431 x 214 x 27 x 7 = 400941198

Therefore, the lowest common multiple of 431,214,621,161 is 400941198.

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.

431 x 214 x 621 x 161 = 9221647554

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.

431 : 1, 431

214 : 1, 2, 107, 214

621 : 1, 3, 9, 23, 27, 69, 207, 621

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,214,621,161, is 1.

Now, the common factors can be found like this.

431:431

214:2x 107

621:3x 3x 3x 23

161:7x 23

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

23 = 23

Therefore, the value for common factors is 23.

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 = 9221647554/(1x23)

LCM = 9221647554/23

LCM = 400941198

Thus, we can understand that the LCM of 431,214,621,161 is 400941198.
