Calculate the LCM of 608,130,978,405

Given numbers are 608,130,978,405

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

The LCM of 608,130,978,405 is 521782560.

Find LCM of 608,130,978,405 with Prime Factorization


2 608, 130, 978, 405
3 304, 65, 489, 405
5 304, 65, 163, 135
304, 13, 163, 27

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

2 x 3 x 5 x 304 x 13 x 163 x 27 = 521782560

Therefore, the lowest common multiple of 608,130,978,405 is 521782560.

LCM Formula to Find Lowest Common Multiple of 608,130,978,405

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.

608 x 130 x 978 x 405 = 31306953600

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.

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

130 : 1, 2, 5, 10, 13, 26, 65, 130

978 : 1, 2, 3, 6, 163, 326, 489, 978

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 608,130,978,405, is 1.

Now, the common factors can be found like this.

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

130:2x 5x 13

978:2x 3x 163

405:3x 3x 3x 3x 5

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

2x 2x 3x 5 = 60

Therefore, the value for common factors is 60.

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 = 31306953600/(1x60)

LCM = 31306953600/60

LCM = 521782560

Thus, we can understand that the LCM of 608,130,978,405 is 521782560.
