Given numbers are 687,779,310,779

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

The LCM of 687,779,310,779 is 165903630.

Find LCM of 687,779,310,779 with Prime Factorization

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

19 x 41 x 687 x 1 x 310 x 1 = 165903630

Therefore, the lowest common multiple of 687,779,310,779 is 165903630.

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.

687 x 779 x 310 x 779 = 129238927770

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.

687 : 1, 3, 229, 687

779 : 1, 19, 41, 779

310 : 1, 2, 5, 10, 31, 62, 155, 310

779 : 1, 19, 41, 779

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,779,310,779, is 1.

Now, the common factors can be found like this.

687:3x 229

779:19x 41

310:2x 5x 31

779:19x 41

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

19x 41 = 779

Therefore, the value for common factors is 779.

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 = 129238927770/(1x779)

LCM = 129238927770/779

LCM = 165903630

Thus, we can understand that the LCM of 687,779,310,779 is 165903630.
