Given numbers are 257,322,542,426

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

The LCM of 257,322,542,426 is 4776809142.

Find LCM of 257,322,542,426 with Prime Factorization

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

2 x 257 x 161 x 271 x 213 = 4776809142

Therefore, the lowest common multiple of 257,322,542,426 is 4776809142.

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.

257 x 322 x 542 x 426 = 19107236568

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.

257 : 1, 257

322 : 1, 2, 7, 14, 23, 46, 161, 322

542 : 1, 2, 271, 542

426 : 1, 2, 3, 6, 71, 142, 213, 426

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,322,542,426, is 1.

Now, the common factors can be found like this.

257:257

322:2x 7x 23

542:2x 271

426:2x 3x 71

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 = 19107236568/(1x4)

LCM = 19107236568/4

LCM = 4776809142

Thus, we can understand that the LCM of 257,322,542,426 is 4776809142.
