Calculate the LCM of 643,772,623,622,727

Given numbers are 643,772,623,622,727

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

The LCM of 643,772,623,622,727 is 69921561714676.

Find LCM of 643,772,623,622,727 with Prime Factorization


2 643, 772, 623, 622, 727
643, 386, 623, 311, 727

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

2 x 643 x 386 x 623 x 311 x 727 = 69921561714676

Therefore, the lowest common multiple of 643,772,623,622,727 is 69921561714676.

LCM Formula to Find Lowest Common Multiple of 643,772,623,622,727

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 772 x 623 x 622 x 727 = 139843123429352

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

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

623 : 1, 7, 89, 623

622 : 1, 2, 311, 622

727 : 1, 727

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,772,623,622,727, is 1.

Now, the common factors can be found like this.

643:643

772:2x 2x 193

623:7x 89

622:2x 311

727:727

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

2 = 2

Therefore, the value for common factors is 2.

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 = 139843123429352/(1x2)

LCM = 139843123429352/2

LCM = 69921561714676

Thus, we can understand that the LCM of 643,772,623,622,727 is 69921561714676.
