Given numbers are 821,681,811,338,274

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

The LCM of 821,681,811,338,274 is 20996571764766.

Find LCM of 821,681,811,338,274 with Prime Factorization

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

2 x 821 x 681 x 811 x 169 x 137 = 20996571764766

Therefore, the lowest common multiple of 821,681,811,338,274 is 20996571764766.

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 681 x 811 x 338 x 274 = 41993143529532

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

681 : 1, 3, 227, 681

811 : 1, 811

338 : 1, 2, 13, 26, 169, 338

274 : 1, 2, 137, 274

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,681,811,338,274, is 1.

Now, the common factors can be found like this.

821:821

681:3x 227

811:811

338:2x 13x 13

274:2x 137

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

2 = 2

Therefore, the value for common factors is 2.

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 = 41993143529532/(1x2)

LCM = 41993143529532/2

LCM = 20996571764766

Thus, we can understand that the LCM of 821,681,811,338,274 is 20996571764766.
