Given numbers are 621,861,961,387

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

The LCM of 621,861,961,387 is 7364874321.

Find LCM of 621,861,961,387 with Prime Factorization

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

3 x 3 x 69 x 287 x 961 x 43 = 7364874321

Therefore, the lowest common multiple of 621,861,961,387 is 7364874321.

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 861 x 961 x 387 = 198851606667

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

861 : 1, 3, 7, 21, 41, 123, 287, 861

961 : 1, 31, 961

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,861,961,387, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

861:3x 7x 41

961:31x 31

387:3x 3x 43

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 = 198851606667/(1x27)

LCM = 198851606667/27

LCM = 7364874321

Thus, we can understand that the LCM of 621,861,961,387 is 7364874321.
