Given numbers are 626,631,790,905

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

The LCM of 626,631,790,905 is 28240953970.

Find LCM of 626,631,790,905 with Prime Factorization

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

2 x 5 x 313 x 631 x 79 x 181 = 28240953970

Therefore, the lowest common multiple of 626,631,790,905 is 28240953970.

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.

626 x 631 x 790 x 905 = 282409539700

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.

626 : 1, 2, 313, 626

631 : 1, 631

790 : 1, 2, 5, 10, 79, 158, 395, 790

905 : 1, 5, 181, 905

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,631,790,905, is 1.

Now, the common factors can be found like this.

626:2x 313

631:631

790:2x 5x 79

905:5x 181

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 282409539700/(1x10)

LCM = 282409539700/10

LCM = 28240953970

Thus, we can understand that the LCM of 626,631,790,905 is 28240953970.
