Given numbers are 821,77,182

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

The LCM of 821,77,182 is 1643642.

Find LCM of 821,77,182 with Prime Factorization

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

7 x 821 x 11 x 26 = 1643642

Therefore, the lowest common multiple of 821,77,182 is 1643642.

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 77 x 182 = 11505494

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

77 : 1, 7, 11, 77

182 : 1, 2, 7, 13, 14, 26, 91, 182

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,77,182, is 1.

Now, the common factors can be found like this.

821:821

77:7x 11

182:2x 7x 13

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

7 = 7

Therefore, the value for common factors is 7.

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 = 11505494/(1x7)

LCM = 11505494/7

LCM = 1643642

Thus, we can understand that the LCM of 821,77,182 is 1643642.

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

• LCM of 579, 18, 348
• LCM of 551, 16, 999
