Given numbers are 161,211,407,407

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

The LCM of 161,211,407,407 is 13826197.

Find LCM of 161,211,407,407 with Prime Factorization

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

11 x 37 x 161 x 211 x 1 x 1 = 13826197

Therefore, the lowest common multiple of 161,211,407,407 is 13826197.

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.

161 x 211 x 407 x 407 = 5627262179

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.

161 : 1, 7, 23, 161

211 : 1, 211

407 : 1, 11, 37, 407

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,211,407,407, is 1.

Now, the common factors can be found like this.

161:7x 23

211:211

407:11x 37

407:11x 37

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

11x 37 = 407

Therefore, the value for common factors is 407.

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 = 5627262179/(1x407)

LCM = 5627262179/407

LCM = 13826197

Thus, we can understand that the LCM of 161,211,407,407 is 13826197.

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

• LCM of 704, 399, 454, 150
