Given numbers are 278,129,129,931

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

The LCM of 278,129,129,931 is 33387522.

Find LCM of 278,129,129,931 with Prime Factorization

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

3 x 43 x 278 x 1 x 1 x 931 = 33387522

Therefore, the lowest common multiple of 278,129,129,931 is 33387522.

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.

278 x 129 x 129 x 931 = 4306990338

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.

278 : 1, 2, 139, 278

129 : 1, 3, 43, 129

129 : 1, 3, 43, 129

931 : 1, 7, 19, 49, 133, 931

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,129,129,931, is 1.

Now, the common factors can be found like this.

278:2x 139

129:3x 43

129:3x 43

931:7x 7x 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 43 = 129

Therefore, the value for common factors is 129.

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 = 4306990338/(1x129)

LCM = 4306990338/129

LCM = 33387522

Thus, we can understand that the LCM of 278,129,129,931 is 33387522.
