Calculate the LCM of 620,608,487,343

Given numbers are 620,608,487,343

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

The LCM of 620,608,487,343 is 15741943840.

Find LCM of 620,608,487,343 with Prime Factorization


2 620, 608, 487, 343
2 310, 304, 487, 343
155, 152, 487, 343

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

2 x 2 x 155 x 152 x 487 x 343 = 15741943840

Therefore, the lowest common multiple of 620,608,487,343 is 15741943840.

LCM Formula to Find Lowest Common Multiple of 620,608,487,343

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.

620 x 608 x 487 x 343 = 62967775360

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608

487 : 1, 487

343 : 1, 7, 49, 343

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,608,487,343, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

608:2x 2x 2x 2x 2x 19

487:487

343:7x 7x 7

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 = 62967775360/(1x4)

LCM = 62967775360/4

LCM = 15741943840

Thus, we can understand that the LCM of 620,608,487,343 is 15741943840.
