Given numbers are 97,99,99,97,621

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

The LCM of 97,99,99,97,621 is 662607.

Find LCM of 97,99,99,97,621 with Prime Factorization

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

3 x 3 x 11 x 97 x 1 x 1 x 1 x 1 x 69 = 662607

Therefore, the lowest common multiple of 97,99,99,97,621 is 662607.

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.

97 x 99 x 99 x 97 x 621 = 57267135189

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.

97 : 1, 97

99 : 1, 3, 9, 11, 33, 99

99 : 1, 3, 9, 11, 33, 99

97 : 1, 97

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 97,99,99,97,621, is 1.

Now, the common factors can be found like this.

97:97

99:3x 3x 11

99:3x 3x 11

97:97

621:3x 3x 3x 23

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 3x 3x 11x 97 = 86427

Therefore, the value for common factors is 86427.

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 = 57267135189/(1x86427)

LCM = 57267135189/86427

LCM = 662607

Thus, we can understand that the LCM of 97,99,99,97,621 is 662607.
