Given numbers are 775,644,816,178

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

The LCM of 775,644,816,178 is 9061659600.

Find LCM of 775,644,816,178 with Prime Factorization

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

2 x 2 x 775 x 161 x 204 x 89 = 9061659600

Therefore, the lowest common multiple of 775,644,816,178 is 9061659600.

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.

775 x 644 x 816 x 178 = 72493276800

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.

775 : 1, 5, 25, 31, 155, 775

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

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

178 : 1, 2, 89, 178

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,644,816,178, is 1.

Now, the common factors can be found like this.

775:5x 5x 31

644:2x 2x 7x 23

816:2x 2x 2x 2x 3x 17

178:2x 89

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 2 = 8

Therefore, the value for common factors is 8.

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 = 72493276800/(1x8)

LCM = 72493276800/8

LCM = 9061659600

Thus, we can understand that the LCM of 775,644,816,178 is 9061659600.
