Given numbers are 643,643,131,239

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

The LCM of 643,643,131,239 is 20131687.

Find LCM of 643,643,131,239 with Prime Factorization

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

643 x 1 x 1 x 131 x 239 = 20131687

Therefore, the lowest common multiple of 643,643,131,239 is 20131687.

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 643 x 131 x 239 = 12944674741

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

643 : 1, 643

131 : 1, 131

239 : 1, 239

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,643,131,239, is 1.

Now, the common factors can be found like this.

643:643

643:643

131:131

239:239

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 = 12944674741/(1x643)

LCM = 12944674741/643

LCM = 20131687

Thus, we can understand that the LCM of 643,643,131,239 is 20131687.
