Given numbers are 778,780,208,230,664

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

The LCM of 778,780,208,230,664 is 2316915120.

Find LCM of 778,780,208,230,664 with Prime Factorization

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

2 x 2 x 2 x 5 x 13 x 389 x 3 x 2 x 23 x 83 = 2316915120

Therefore, the lowest common multiple of 778,780,208,230,664 is 2316915120.

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.

778 x 780 x 208 x 230 x 664 = 19276733798400

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.

778 : 1, 2, 389, 778

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

230 : 1, 2, 5, 10, 23, 46, 115, 230

664 : 1, 2, 4, 8, 83, 166, 332, 664

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,780,208,230,664, is 2.

Now, the common factors can be found like this.

778:2x 389

780:2x 2x 3x 5x 13

208:2x 2x 2x 2x 13

230:2x 5x 23

664:2x 2x 2x 83

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 5x 13 = 4160

Therefore, the value for common factors is 4160.

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 = 19276733798400/(2x4160)

LCM = 19276733798400/8320

LCM = 2316915120

Thus, we can understand that the LCM of 778,780,208,230,664 is 2316915120.
