Given numbers are 623,709,869,445

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

The LCM of 623,709,869,445 is 1919216915.

Find LCM of 623,709,869,445 with Prime Factorization

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

89 x 7 x 709 x 869 x 5 = 1919216915

Therefore, the lowest common multiple of 623,709,869,445 is 1919216915.

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.

623 x 709 x 869 x 445 = 170810305435

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.

623 : 1, 7, 89, 623

709 : 1, 709

869 : 1, 11, 79, 869

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,709,869,445, is 1.

Now, the common factors can be found like this.

623:7x 89

709:709

869:11x 79

445:5x 89

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

89 = 89

Therefore, the value for common factors is 89.

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 = 170810305435/(1x89)

LCM = 170810305435/89

LCM = 1919216915

Thus, we can understand that the LCM of 623,709,869,445 is 1919216915.
