Given numbers are 139,102,281,122

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

The LCM of 139,102,281,122 is 243025098.

Find LCM of 139,102,281,122 with Prime Factorization

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

2 x 139 x 51 x 281 x 61 = 243025098

Therefore, the lowest common multiple of 139,102,281,122 is 243025098.

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.

139 x 102 x 281 x 122 = 486050196

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.

139 : 1, 139

102 : 1, 2, 3, 6, 17, 34, 51, 102

281 : 1, 281

122 : 1, 2, 61, 122

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 139,102,281,122, is 1.

Now, the common factors can be found like this.

139:139

102:2x 3x 17

281:281

122:2x 61

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

2 = 2

Therefore, the value for common factors is 2.

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 = 486050196/(1x2)

LCM = 486050196/2

LCM = 243025098

Thus, we can understand that the LCM of 139,102,281,122 is 243025098.
