Given numbers are 643,818,643,371

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

The LCM of 643,818,643,371 is 195136354.

Find LCM of 643,818,643,371 with Prime Factorization

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

643 x 1 x 818 x 1 x 371 = 195136354

Therefore, the lowest common multiple of 643,818,643,371 is 195136354.

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.

643 x 818 x 643 x 371 = 125472675622

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.

643 : 1, 643

818 : 1, 2, 409, 818

643 : 1, 643

371 : 1, 7, 53, 371

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,818,643,371, is 1.

Now, the common factors can be found like this.

643:643

818:2x 409

643:643

371:7x 53

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

643 = 643

Therefore, the value for common factors is 643.

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 = 125472675622/(1x643)

LCM = 125472675622/643

LCM = 195136354

Thus, we can understand that the LCM of 643,818,643,371 is 195136354.
