Given numbers are 626,478,734,781

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

The LCM of 626,478,734,781 is 42883411978.

Find LCM of 626,478,734,781 with Prime Factorization

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

2 x 313 x 239 x 367 x 781 = 42883411978

Therefore, the lowest common multiple of 626,478,734,781 is 42883411978.

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.

626 x 478 x 734 x 781 = 171533647912

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.

626 : 1, 2, 313, 626

478 : 1, 2, 239, 478

734 : 1, 2, 367, 734

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,478,734,781, is 1.

Now, the common factors can be found like this.

626:2x 313

478:2x 239

734:2x 367

781:11x 71

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 171533647912/(1x4)

LCM = 171533647912/4

LCM = 42883411978

Thus, we can understand that the LCM of 626,478,734,781 is 42883411978.
