Given numbers are 401,687,942

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

The LCM of 401,687,942 is 86502918.

Find LCM of 401,687,942 with Prime Factorization

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

3 x 401 x 229 x 314 = 86502918

Therefore, the lowest common multiple of 401,687,942 is 86502918.

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.

401 x 687 x 942 = 259508754

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.

401 : 1, 401

687 : 1, 3, 229, 687

942 : 1, 2, 3, 6, 157, 314, 471, 942

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,687,942, is 1.

Now, the common factors can be found like this.

401:401

687:3x 229

942:2x 3x 157

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

3 = 3

Therefore, the value for common factors is 3.

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 = 259508754/(1x3)

LCM = 259508754/3

LCM = 86502918

Thus, we can understand that the LCM of 401,687,942 is 86502918.

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

• LCM of 894, 416, 774
• LCM of 796, 444, 291
