Given numbers are 621,691,381,791

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

The LCM of 621,691,381,791 is 43107203727.

Find LCM of 621,691,381,791 with Prime Factorization

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

3 x 207 x 691 x 127 x 791 = 43107203727

Therefore, the lowest common multiple of 621,691,381,791 is 43107203727.

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 691 x 381 x 791 = 129321611181

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

691 : 1, 691

381 : 1, 3, 127, 381

791 : 1, 7, 113, 791

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,691,381,791, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

691:691

381:3x 127

791:7x 113

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

3 = 3

Therefore, the value for common factors is 3.

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 = 129321611181/(1x3)

LCM = 129321611181/3

LCM = 43107203727

Thus, we can understand that the LCM of 621,691,381,791 is 43107203727.
