Given numbers are 621,789,167,657

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

The LCM of 621,789,167,657 is 1991070693.

Find LCM of 621,789,167,657 with Prime Factorization

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

3 x 3 x 69 x 263 x 167 x 73 = 1991070693

Therefore, the lowest common multiple of 621,789,167,657 is 1991070693.

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.

621 x 789 x 167 x 657 = 53758908711

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.

621 : 1, 3, 9, 23, 27, 69, 207, 621

789 : 1, 3, 263, 789

167 : 1, 167

657 : 1, 3, 9, 73, 219, 657

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,789,167,657, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

789:3x 263

167:167

657:3x 3x 73

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 53758908711/(1x27)

LCM = 53758908711/27

LCM = 1991070693

Thus, we can understand that the LCM of 621,789,167,657 is 1991070693.
