Given numbers are 628,618,721,922

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

The LCM of 628,618,721,922 is 626205804.

Find LCM of 628,618,721,922 with Prime Factorization

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

2 x 103 x 314 x 3 x 7 x 461 = 626205804

Therefore, the lowest common multiple of 628,618,721,922 is 626205804.

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 618 x 721 x 922 = 257996791248

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

618 : 1, 2, 3, 6, 103, 206, 309, 618

721 : 1, 7, 103, 721

922 : 1, 2, 461, 922

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,618,721,922, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

618:2x 3x 103

721:7x 103

922:2x 461

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 103 = 412

Therefore, the value for common factors is 412.

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 = 257996791248/(1x412)

LCM = 257996791248/412

LCM = 626205804

Thus, we can understand that the LCM of 628,618,721,922 is 626205804.
