Given numbers are 620,167,128,385

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

The LCM of 620,167,128,385 is 255122560.

Find LCM of 620,167,128,385 with Prime Factorization

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

2 x 2 x 5 x 31 x 167 x 32 x 77 = 255122560

Therefore, the lowest common multiple of 620,167,128,385 is 255122560.

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.

620 x 167 x 128 x 385 = 5102451200

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

167 : 1, 167

128 : 1, 2, 4, 8, 16, 32, 64, 128

385 : 1, 5, 7, 11, 35, 55, 77, 385

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,167,128,385, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

167:167

128:2x 2x 2x 2x 2x 2x 2

385:5x 7x 11

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 5102451200/(1x20)

LCM = 5102451200/20

LCM = 255122560

Thus, we can understand that the LCM of 620,167,128,385 is 255122560.
