Given numbers are 821,656,287,181

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

The LCM of 821,656,287,181 is 682375792.

Find LCM of 821,656,287,181 with Prime Factorization

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

41 x 821 x 16 x 7 x 181 = 682375792

Therefore, the lowest common multiple of 821,656,287,181 is 682375792.

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 656 x 287 x 181 = 27977407472

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

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

287 : 1, 7, 41, 287

181 : 1, 181

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,656,287,181, is 1.

Now, the common factors can be found like this.

821:821

656:2x 2x 2x 2x 41

287:7x 41

181:181

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

41 = 41

Therefore, the value for common factors is 41.

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 = 27977407472/(1x41)

LCM = 27977407472/41

LCM = 682375792

Thus, we can understand that the LCM of 821,656,287,181 is 682375792.
