Given numbers are 647,647,871,607

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

The LCM of 647,647,871,607 is 342066959.

Find LCM of 647,647,871,607 with Prime Factorization

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

647 x 1 x 1 x 871 x 607 = 342066959

Therefore, the lowest common multiple of 647,647,871,607 is 342066959.

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.

647 x 647 x 871 x 607 = 221317322473

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.

647 : 1, 647

647 : 1, 647

871 : 1, 13, 67, 871

607 : 1, 607

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,647,871,607, is 1.

Now, the common factors can be found like this.

647:647

647:647

871:13x 67

607:607

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

647 = 647

Therefore, the value for common factors is 647.

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 = 221317322473/(1x647)

LCM = 221317322473/647

LCM = 342066959

Thus, we can understand that the LCM of 647,647,871,607 is 342066959.
