Given numbers are 228,782,644,172,440

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

The LCM of 228,782,644,172,440 is 2951690280.

Find LCM of 228,782,644,172,440 with Prime Factorization

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

2 x 2 x 23 x 57 x 17 x 7 x 43 x 110 = 2951690280

Therefore, the lowest common multiple of 228,782,644,172,440 is 2951690280.

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.

228 x 782 x 644 x 172 x 440 = 8689776184320

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.

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

782 : 1, 2, 17, 23, 34, 46, 391, 782

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

172 : 1, 2, 4, 43, 86, 172

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,782,644,172,440, is 2.

Now, the common factors can be found like this.

228:2x 2x 3x 19

782:2x 17x 23

644:2x 2x 7x 23

172:2x 2x 43

440:2x 2x 2x 5x 11

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 2x 23 = 1472

Therefore, the value for common factors is 1472.

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 = 8689776184320/(2x1472)

LCM = 8689776184320/2944

LCM = 2951690280

Thus, we can understand that the LCM of 228,782,644,172,440 is 2951690280.
