Given numbers are 166,218,421

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

The LCM of 166,218,421 is 7617574.

Find LCM of 166,218,421 with Prime Factorization

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

2 x 83 x 109 x 421 = 7617574

Therefore, the lowest common multiple of 166,218,421 is 7617574.

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.

166 x 218 x 421 = 15235148

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.

166 : 1, 2, 83, 166

218 : 1, 2, 109, 218

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 166,218,421, is 1.

Now, the common factors can be found like this.

166:2x 83

218:2x 109

421:421

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 = 15235148/(1x2)

LCM = 15235148/2

LCM = 7617574

Thus, we can understand that the LCM of 166,218,421 is 7617574.

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

• LCM of 849, 257, 456
• LCM of 307, 564, 328
