Given numbers are 427,288,557,163,646

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

The LCM of 427,288,557,163,646 is 3606331827168.

Find LCM of 427,288,557,163,646 with Prime Factorization

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

2 x 427 x 144 x 557 x 163 x 323 = 3606331827168

Therefore, the lowest common multiple of 427,288,557,163,646 is 3606331827168.

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 288 x 557 x 163 x 646 = 7212663654336

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

288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288

557 : 1, 557

163 : 1, 163

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,288,557,163,646, is 1.

Now, the common factors can be found like this.

427:7x 61

288:2x 2x 2x 2x 2x 3x 3

557:557

163:163

646:2x 17x 19

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 = 7212663654336/(1x2)

LCM = 7212663654336/2

LCM = 3606331827168

Thus, we can understand that the LCM of 427,288,557,163,646 is 3606331827168.
