Given numbers are 163,157,129,378

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

The LCM of 163,157,129,378 is 415956114.

Find LCM of 163,157,129,378 with Prime Factorization

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

3 x 163 x 157 x 43 x 126 = 415956114

Therefore, the lowest common multiple of 163,157,129,378 is 415956114.

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.

163 x 157 x 129 x 378 = 1247868342

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.

163 : 1, 163

157 : 1, 157

129 : 1, 3, 43, 129

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,157,129,378, is 1.

Now, the common factors can be found like this.

163:163

157:157

129:3x 43

378:2x 3x 3x 3x 7

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

3 = 3

Therefore, the value for common factors is 3.

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 = 1247868342/(1x3)

LCM = 1247868342/3

LCM = 415956114

Thus, we can understand that the LCM of 163,157,129,378 is 415956114.

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

• LCM of 897, 716, 100, 976
