Given numbers are 407,771,771

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

The LCM of 407,771,771 is 313797.

Find LCM of 407,771,771 with Prime Factorization

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

3 x 257 x 407 x 1 x 1 = 313797

Therefore, the lowest common multiple of 407,771,771 is 313797.

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.

407 x 771 x 771 = 241937487

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.

407 : 1, 11, 37, 407

771 : 1, 3, 257, 771

771 : 1, 3, 257, 771

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,771,771, is 1.

Now, the common factors can be found like this.

407:11x 37

771:3x 257

771:3x 257

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

3x 257 = 771

Therefore, the value for common factors is 771.

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 = 241937487/(1x771)

LCM = 241937487/771

LCM = 313797

Thus, we can understand that the LCM of 407,771,771 is 313797.

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

• LCM of 525, 908, 672
• LCM of 637, 679, 338
