Given numbers are 768,183,161,128,778

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

The LCM of 768,183,161,128,778 is 2934043392.

Find LCM of 768,183,161,128,778 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 2 x 61 x 161 x 1 x 389 = 2934043392

Therefore, the lowest common multiple of 768,183,161,128,778 is 2934043392.

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.

768 x 183 x 161 x 128 x 778 = 2253345325056

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.

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

183 : 1, 3, 61, 183

161 : 1, 7, 23, 161

128 : 1, 2, 4, 8, 16, 32, 64, 128

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,183,161,128,778, is 1.

Now, the common factors can be found like this.

768:2x 2x 2x 2x 2x 2x 2x 2x 3

183:3x 61

161:7x 23

128:2x 2x 2x 2x 2x 2x 2

778:2x 389

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 2x 2x 3 = 768

Therefore, the value for common factors is 768.

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 = 2253345325056/(1x768)

LCM = 2253345325056/768

LCM = 2934043392

Thus, we can understand that the LCM of 768,183,161,128,778 is 2934043392.
