Given numbers are 102,928,646,644,772

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

The LCM of 102,928,646,644,772 is 27941835936.

Find LCM of 102,928,646,644,772 with Prime Factorization

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

2 x 2 x 17 x 3 x 232 x 19 x 161 x 193 = 27941835936

Therefore, the lowest common multiple of 102,928,646,644,772 is 27941835936.

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.

102 x 928 x 646 x 644 x 772 = 30400717498368

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.

102 : 1, 2, 3, 6, 17, 34, 51, 102

928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928

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

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,928,646,644,772, is 2.

Now, the common factors can be found like this.

102:2x 3x 17

928:2x 2x 2x 2x 2x 29

646:2x 17x 19

644:2x 2x 7x 23

772:2x 2x 193

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 2x 2x 2x 17 = 544

Therefore, the value for common factors is 544.

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 = 30400717498368/(2x544)

LCM = 30400717498368/1088

LCM = 27941835936

Thus, we can understand that the LCM of 102,928,646,644,772 is 27941835936.
