Given numbers are 228,821,419,821

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

The LCM of 228,821,419,821 is 78431772.

Find LCM of 228,821,419,821 with Prime Factorization

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

821 x 228 x 1 x 419 x 1 = 78431772

Therefore, the lowest common multiple of 228,821,419,821 is 78431772.

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.

228 x 821 x 419 x 821 = 64392484812

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.

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

821 : 1, 821

419 : 1, 419

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,821,419,821, is 1.

Now, the common factors can be found like this.

228:2x 2x 3x 19

821:821

419:419

821:821

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

821 = 821

Therefore, the value for common factors is 821.

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 = 64392484812/(1x821)

LCM = 64392484812/821

LCM = 78431772

Thus, we can understand that the LCM of 228,821,419,821 is 78431772.
