Given numbers are 742,284,129,284

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

The LCM of 742,284,129,284 is 13591956.

Find LCM of 742,284,129,284 with Prime Factorization

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

2 x 2 x 71 x 371 x 1 x 129 x 1 = 13591956

Therefore, the lowest common multiple of 742,284,129,284 is 13591956.

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.

742 x 284 x 129 x 284 = 7720231008

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.

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

284 : 1, 2, 4, 71, 142, 284

129 : 1, 3, 43, 129

284 : 1, 2, 4, 71, 142, 284

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,284,129,284, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

284:2x 2x 71

129:3x 43

284:2x 2x 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 2x 2x 71 = 568

Therefore, the value for common factors is 568.

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 = 7720231008/(1x568)

LCM = 7720231008/568

LCM = 13591956

Thus, we can understand that the LCM of 742,284,129,284 is 13591956.
