Given numbers are 122,129,305

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

The LCM of 122,129,305 is 78690.

Find LCM of 122,129,305 with Prime Factorization

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

61 x 2 x 129 x 5 = 78690

Therefore, the lowest common multiple of 122,129,305 is 78690.

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.

122 x 129 x 305 = 4800090

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.

122 : 1, 2, 61, 122

129 : 1, 3, 43, 129

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,129,305, is 1.

Now, the common factors can be found like this.

122:2x 61

129:3x 43

305:5x 61

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

61 = 61

Therefore, the value for common factors is 61.

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 = 4800090/(1x61)

LCM = 4800090/61

LCM = 78690

Thus, we can understand that the LCM of 122,129,305 is 78690.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 250, 932, 247
• LCM of 486, 921, 562
