Calculate the LCM of 685,647,782,732,779

Given numbers are 685,647,782,732,779

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

The LCM of 685,647,782,732,779 is 98814379597860.

Find LCM of 685,647,782,732,779 with Prime Factorization


2 685, 647, 782, 732, 779
685, 647, 391, 366, 779

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

2 x 685 x 647 x 391 x 366 x 779 = 98814379597860

Therefore, the lowest common multiple of 685,647,782,732,779 is 98814379597860.

LCM Formula to Find Lowest Common Multiple of 685,647,782,732,779

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.

685 x 647 x 782 x 732 x 779 = 197628759195720

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.

685 : 1, 5, 137, 685

647 : 1, 647

782 : 1, 2, 17, 23, 34, 46, 391, 782

732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732

779 : 1, 19, 41, 779

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,647,782,732,779, is 1.

Now, the common factors can be found like this.

685:5x 137

647:647

782:2x 17x 23

732:2x 2x 3x 61

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 197628759195720/(1x2)

LCM = 197628759195720/2

LCM = 98814379597860

Thus, we can understand that the LCM of 685,647,782,732,779 is 98814379597860.
