Calculate the LCM of 770,745,722,904

Given numbers are 770,745,722,904

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

The LCM of 770,745,722,904 is 18720723560.

Find LCM of 770,745,722,904 with Prime Factorization


2 770, 745, 722, 904
5 385, 745, 361, 452
77, 149, 361, 452

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

2 x 5 x 77 x 149 x 361 x 452 = 18720723560

Therefore, the lowest common multiple of 770,745,722,904 is 18720723560.

LCM Formula to Find Lowest Common Multiple of 770,745,722,904

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.

770 x 745 x 722 x 904 = 374414471200

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.

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

745 : 1, 5, 149, 745

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

904 : 1, 2, 4, 8, 113, 226, 452, 904

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,745,722,904, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

745:5x 149

722:2x 19x 19

904:2x 2x 2x 113

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 5 = 20

Therefore, the value for common factors is 20.

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 = 374414471200/(1x20)

LCM = 374414471200/20

LCM = 18720723560

Thus, we can understand that the LCM of 770,745,722,904 is 18720723560.
