Given numbers are 212,742,394,257

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

The LCM of 212,742,394,257 is 75133436.

Find LCM of 212,742,394,257 with Prime Factorization

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

2 x 53 x 2 x 7 x 197 x 257 = 75133436

Therefore, the lowest common multiple of 212,742,394,257 is 75133436.

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.

212 x 742 x 394 x 257 = 15928288432

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.

212 : 1, 2, 4, 53, 106, 212

742 : 1, 2, 7, 14, 53, 106, 371, 742

394 : 1, 2, 197, 394

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,742,394,257, is 1.

Now, the common factors can be found like this.

212:2x 2x 53

742:2x 7x 53

394:2x 197

257:257

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 53 = 212

Therefore, the value for common factors is 212.

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 = 15928288432/(1x212)

LCM = 15928288432/212

LCM = 75133436

Thus, we can understand that the LCM of 212,742,394,257 is 75133436.
