Given numbers are 542,668,731,51

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

The LCM of 542,668,731,51 is 396994404.

Find LCM of 542,668,731,51 with Prime Factorization

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

2 x 17 x 271 x 334 x 43 x 3 = 396994404

Therefore, the lowest common multiple of 542,668,731,51 is 396994404.

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.

542 x 668 x 731 x 51 = 13497809736

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.

542 : 1, 2, 271, 542

668 : 1, 2, 4, 167, 334, 668

731 : 1, 17, 43, 731

51 : 1, 3, 17, 51

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,668,731,51, is 1.

Now, the common factors can be found like this.

542:2x 271

668:2x 2x 167

731:17x 43

51:3x 17

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 13497809736/(1x34)

LCM = 13497809736/34

LCM = 396994404

Thus, we can understand that the LCM of 542,668,731,51 is 396994404.
