Given numbers are 777,556,678,990

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

The LCM of 777,556,678,990 is 8054863740.

Find LCM of 777,556,678,990 with Prime Factorization

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

2 x 3 x 259 x 278 x 113 x 165 = 8054863740

Therefore, the lowest common multiple of 777,556,678,990 is 8054863740.

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.

777 x 556 x 678 x 990 = 289975094640

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.

777 : 1, 3, 7, 21, 37, 111, 259, 777

556 : 1, 2, 4, 139, 278, 556

678 : 1, 2, 3, 6, 113, 226, 339, 678

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,556,678,990, is 1.

Now, the common factors can be found like this.

777:3x 7x 37

556:2x 2x 139

678:2x 3x 113

990:2x 3x 3x 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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 289975094640/(1x36)

LCM = 289975094640/36

LCM = 8054863740

Thus, we can understand that the LCM of 777,556,678,990 is 8054863740.
