Given numbers are 821,172,858,677

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

The LCM of 821,172,858,677 is 41012624796.

Find LCM of 821,172,858,677 with Prime Factorization

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

2 x 821 x 86 x 429 x 677 = 41012624796

Therefore, the lowest common multiple of 821,172,858,677 is 41012624796.

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 172 x 858 x 677 = 82025249592

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

172 : 1, 2, 4, 43, 86, 172

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

677 : 1, 677

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,172,858,677, is 1.

Now, the common factors can be found like this.

821:821

172:2x 2x 43

858:2x 3x 11x 13

677:677

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 = 82025249592/(1x2)

LCM = 82025249592/2

LCM = 41012624796

Thus, we can understand that the LCM of 821,172,858,677 is 41012624796.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 646, 654, 474, 845
