Given numbers are 628,677,840,772

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

The LCM of 628,677,840,772 is 17231572680.

Find LCM of 628,677,840,772 with Prime Factorization

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

2 x 2 x 157 x 677 x 210 x 193 = 17231572680

Therefore, the lowest common multiple of 628,677,840,772 is 17231572680.

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 677 x 840 x 772 = 275705162880

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

677 : 1, 677

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

772 : 1, 2, 4, 193, 386, 772

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,677,840,772, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

677:677

840:2x 2x 2x 3x 5x 7

772:2x 2x 193

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 275705162880/(1x16)

LCM = 275705162880/16

LCM = 17231572680

Thus, we can understand that the LCM of 628,677,840,772 is 17231572680.
