Calculate the LCM of 788,869,165,641

Given numbers are 788,869,165,641

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

The LCM of 788,869,165,641 is 6584082780.

Find LCM of 788,869,165,641 with Prime Factorization


11 788, 869, 165, 641
788, 79, 15, 641

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

11 x 788 x 79 x 15 x 641 = 6584082780

Therefore, the lowest common multiple of 788,869,165,641 is 6584082780.

LCM Formula to Find Lowest Common Multiple of 788,869,165,641

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.

788 x 869 x 165 x 641 = 72424910580

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.

788 : 1, 2, 4, 197, 394, 788

869 : 1, 11, 79, 869

165 : 1, 3, 5, 11, 15, 33, 55, 165

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,869,165,641, is 1.

Now, the common factors can be found like this.

788:2x 2x 197

869:11x 79

165:3x 5x 11

641:641

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

11 = 11

Therefore, the value for common factors is 11.

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 = 72424910580/(1x11)

LCM = 72424910580/11

LCM = 6584082780

Thus, we can understand that the LCM of 788,869,165,641 is 6584082780.
