Given numbers are 821,226,198,789

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

The LCM of 821,226,198,789 is 4831061202.

Find LCM of 821,226,198,789 with Prime Factorization

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

2 x 3 x 821 x 113 x 33 x 263 = 4831061202

Therefore, the lowest common multiple of 821,226,198,789 is 4831061202.

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.

821 x 226 x 198 x 789 = 28986367212

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.

821 : 1, 821

226 : 1, 2, 113, 226

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

789 : 1, 3, 263, 789

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,226,198,789, is 1.

Now, the common factors can be found like this.

821:821

226:2x 113

198:2x 3x 3x 11

789:3x 263

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 28986367212/(1x6)

LCM = 28986367212/6

LCM = 4831061202

Thus, we can understand that the LCM of 821,226,198,789 is 4831061202.
