Given numbers are 642,515,103,281

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

The LCM of 642,515,103,281 is 92907030.

Find LCM of 642,515,103,281 with Prime Factorization

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

103 x 642 x 5 x 1 x 281 = 92907030

Therefore, the lowest common multiple of 642,515,103,281 is 92907030.

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.

642 x 515 x 103 x 281 = 9569424090

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

515 : 1, 5, 103, 515

103 : 1, 103

281 : 1, 281

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,515,103,281, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

515:5x 103

103:103

281:281

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

103 = 103

Therefore, the value for common factors is 103.

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 = 9569424090/(1x103)

LCM = 9569424090/103

LCM = 92907030

Thus, we can understand that the LCM of 642,515,103,281 is 92907030.
