Given numbers are 427,608,772,409

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

The LCM of 427,608,772,409 is 20493308192.

Find LCM of 427,608,772,409 with Prime Factorization

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

2 x 2 x 427 x 152 x 193 x 409 = 20493308192

Therefore, the lowest common multiple of 427,608,772,409 is 20493308192.

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.

427 x 608 x 772 x 409 = 81973232768

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.

427 : 1, 7, 61, 427

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

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

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,608,772,409, is 1.

Now, the common factors can be found like this.

427:7x 61

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

772:2x 2x 193

409:409

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 = 81973232768/(1x4)

LCM = 81973232768/4

LCM = 20493308192

Thus, we can understand that the LCM of 427,608,772,409 is 20493308192.
