Given numbers are 920,167,121,391

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

The LCM of 920,167,121,391 is 316037480.

Find LCM of 920,167,121,391 with Prime Factorization

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

23 x 40 x 167 x 121 x 17 = 316037480

Therefore, the lowest common multiple of 920,167,121,391 is 316037480.

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.

920 x 167 x 121 x 391 = 7268862040

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

167 : 1, 167

121 : 1, 11, 121

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,167,121,391, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

167:167

121:11x 11

391:17x 23

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

23 = 23

Therefore, the value for common factors is 23.

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 = 7268862040/(1x23)

LCM = 7268862040/23

LCM = 316037480

Thus, we can understand that the LCM of 920,167,121,391 is 316037480.
