Calculate the LCM of 398,171,462,187

Given numbers are 398,171,462,187

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

The LCM of 398,171,462,187 is 89087922.

Find LCM of 398,171,462,187 with Prime Factorization


2 398, 171, 462, 187
3 199, 171, 231, 187
11 199, 57, 77, 187
199, 57, 7, 17

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

2 x 3 x 11 x 199 x 57 x 7 x 17 = 89087922

Therefore, the lowest common multiple of 398,171,462,187 is 89087922.

LCM Formula to Find Lowest Common Multiple of 398,171,462,187

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.

398 x 171 x 462 x 187 = 5879802852

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.

398 : 1, 2, 199, 398

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

462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462

187 : 1, 11, 17, 187

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,171,462,187, is 1.

Now, the common factors can be found like this.

398:2x 199

171:3x 3x 19

462:2x 3x 7x 11

187:11x 17

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

2x 3x 11 = 66

Therefore, the value for common factors is 66.

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 = 5879802852/(1x66)

LCM = 5879802852/66

LCM = 89087922

Thus, we can understand that the LCM of 398,171,462,187 is 89087922.
