Given numbers are 626,436,770,990

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

The LCM of 626,436,770,990 is 472861620.

Find LCM of 626,436,770,990 with Prime Factorization

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

2 x 5 x 11 x 313 x 218 x 7 x 9 = 472861620

Therefore, the lowest common multiple of 626,436,770,990 is 472861620.

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 436 x 770 x 990 = 208059112800

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

436 : 1, 2, 4, 109, 218, 436

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,436,770,990, is 2.

Now, the common factors can be found like this.

626:2x 313

436:2x 2x 109

770:2x 5x 7x 11

990:2x 3x 3x 5x 11

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

2x 2x 5x 11 = 220

Therefore, the value for common factors is 220.

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 = 208059112800/(2x220)

LCM = 208059112800/440

LCM = 472861620

Thus, we can understand that the LCM of 626,436,770,990 is 472861620.
