Calculate the LCM of 769,722,788,842

Given numbers are 769,722,788,842

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

The LCM of 769,722,788,842 is 92096230532.

Find LCM of 769,722,788,842 with Prime Factorization


2 769, 722, 788, 842
769, 361, 394, 421

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

2 x 769 x 361 x 394 x 421 = 92096230532

Therefore, the lowest common multiple of 769,722,788,842 is 92096230532.

LCM Formula to Find Lowest Common Multiple of 769,722,788,842

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.

769 x 722 x 788 x 842 = 368384922128

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.

769 : 1, 769

722 : 1, 2, 19, 38, 361, 722

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

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,722,788,842, is 1.

Now, the common factors can be found like this.

769:769

722:2x 19x 19

788:2x 2x 197

842:2x 421

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 368384922128/(1x4)

LCM = 368384922128/4

LCM = 92096230532

Thus, we can understand that the LCM of 769,722,788,842 is 92096230532.
