Given numbers are 892,212,257,643

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

The LCM of 892,212,257,643 is 7812406276.

Find LCM of 892,212,257,643 with Prime Factorization

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

2 x 2 x 223 x 53 x 257 x 643 = 7812406276

Therefore, the lowest common multiple of 892,212,257,643 is 7812406276.

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.

892 x 212 x 257 x 643 = 31249625104

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.

892 : 1, 2, 4, 223, 446, 892

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

257 : 1, 257

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 892,212,257,643, is 1.

Now, the common factors can be found like this.

892:2x 2x 223

212:2x 2x 53

257:257

643:643

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 = 31249625104/(1x4)

LCM = 31249625104/4

LCM = 7812406276

Thus, we can understand that the LCM of 892,212,257,643 is 7812406276.
