Given numbers are 856,661,661

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

The LCM of 856,661,661 is 565816.

Find LCM of 856,661,661 with Prime Factorization

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

661 x 856 x 1 x 1 = 565816

Therefore, the lowest common multiple of 856,661,661 is 565816.

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.

856 x 661 x 661 = 374004376

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

661 : 1, 661

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,661,661, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

661:661

661:661

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

661 = 661

Therefore, the value for common factors is 661.

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 = 374004376/(1x661)

LCM = 374004376/661

LCM = 565816

Thus, we can understand that the LCM of 856,661,661 is 565816.

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

• LCM of 329, 132, 742
• LCM of 485, 285, 196
