Given numbers are 311,772,398,965

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

The LCM of 311,772,398,965 is 238891540.

Find LCM of 311,772,398,965 with Prime Factorization

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

2 x 193 x 311 x 2 x 199 x 5 = 238891540

Therefore, the lowest common multiple of 311,772,398,965 is 238891540.

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.

311 x 772 x 398 x 965 = 92212134440

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.

311 : 1, 311

772 : 1, 2, 4, 193, 386, 772

398 : 1, 2, 199, 398

965 : 1, 5, 193, 965

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,772,398,965, is 1.

Now, the common factors can be found like this.

311:311

772:2x 2x 193

398:2x 199

965:5x 193

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

2x 193 = 386

Therefore, the value for common factors is 386.

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 = 92212134440/(1x386)

LCM = 92212134440/386

LCM = 238891540

Thus, we can understand that the LCM of 311,772,398,965 is 238891540.
