Given numbers are 621,194,182,428

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

The LCM of 621,194,182,428 is 2346110676.

Find LCM of 621,194,182,428 with Prime Factorization

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

2 x 621 x 97 x 91 x 214 = 2346110676

Therefore, the lowest common multiple of 621,194,182,428 is 2346110676.

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.

621 x 194 x 182 x 428 = 9384442704

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.

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

194 : 1, 2, 97, 194

182 : 1, 2, 7, 13, 14, 26, 91, 182

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,194,182,428, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

194:2x 97

182:2x 7x 13

428:2x 2x 107

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 = 9384442704/(1x4)

LCM = 9384442704/4

LCM = 2346110676

Thus, we can understand that the LCM of 621,194,182,428 is 2346110676.
