Given numbers are 171,196,361,57

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

The LCM of 171,196,361,57 is 636804.

Find LCM of 171,196,361,57 with Prime Factorization

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

3 x 19 x 3 x 196 x 1 x 19 = 636804

Therefore, the lowest common multiple of 171,196,361,57 is 636804.

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.

171 x 196 x 361 x 57 = 689658732

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.

171 : 1, 3, 9, 19, 57, 171

196 : 1, 2, 4, 7, 14, 28, 49, 98, 196

361 : 1, 19, 361

57 : 1, 3, 19, 57

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,196,361,57, is 1.

Now, the common factors can be found like this.

171:3x 3x 19

196:2x 2x 7x 7

361:19x 19

57:3x 19

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

3x 19x 19 = 1083

Therefore, the value for common factors is 1083.

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 = 689658732/(1x1083)

LCM = 689658732/1083

LCM = 636804

Thus, we can understand that the LCM of 171,196,361,57 is 636804.

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

• LCM of 474, 724, 989, 61
