Given numbers are 620,985,194,538

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

The LCM of 620,985,194,538 is 3186999020.

Find LCM of 620,985,194,538 with Prime Factorization

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

2 x 5 x 62 x 197 x 97 x 269 = 3186999020

Therefore, the lowest common multiple of 620,985,194,538 is 3186999020.

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.

620 x 985 x 194 x 538 = 63739980400

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

985 : 1, 5, 197, 985

194 : 1, 2, 97, 194

538 : 1, 2, 269, 538

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,985,194,538, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

985:5x 197

194:2x 97

538:2x 269

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 63739980400/(1x20)

LCM = 63739980400/20

LCM = 3186999020

Thus, we can understand that the LCM of 620,985,194,538 is 3186999020.
