Given numbers are 921,338,122

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

The LCM of 921,338,122 is 18989178.

Find LCM of 921,338,122 with Prime Factorization

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

2 x 921 x 169 x 61 = 18989178

Therefore, the lowest common multiple of 921,338,122 is 18989178.

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.

921 x 338 x 122 = 37978356

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.

921 : 1, 3, 307, 921

338 : 1, 2, 13, 26, 169, 338

122 : 1, 2, 61, 122

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,338,122, is 1.

Now, the common factors can be found like this.

921:3x 307

338:2x 13x 13

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 = 37978356/(1x2)

LCM = 37978356/2

LCM = 18989178

Thus, we can understand that the LCM of 921,338,122 is 18989178.

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

• LCM of 938, 881, 823
• LCM of 196, 561, 837
