Given numbers are 628,629,242,555

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

The LCM of 628,629,242,555 is 716946780.

Find LCM of 628,629,242,555 with Prime Factorization

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

2 x 37 x 314 x 17 x 121 x 15 = 716946780

Therefore, the lowest common multiple of 628,629,242,555 is 716946780.

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.

628 x 629 x 242 x 555 = 53054061720

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.

628 : 1, 2, 4, 157, 314, 628

629 : 1, 17, 37, 629

242 : 1, 2, 11, 22, 121, 242

555 : 1, 3, 5, 15, 37, 111, 185, 555

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,629,242,555, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

629:17x 37

242:2x 11x 11

555:3x 5x 37

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

2x 37 = 74

Therefore, the value for common factors is 74.

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 = 53054061720/(1x74)

LCM = 53054061720/74

LCM = 716946780

Thus, we can understand that the LCM of 628,629,242,555 is 716946780.
