Calculate the LCM of 745,678,722,631

Given numbers are 745,678,722,631

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

The LCM of 745,678,722,631 is 115059512010.

Find LCM of 745,678,722,631 with Prime Factorization


2 745, 678, 722, 631
745, 339, 361, 631

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

2 x 745 x 339 x 361 x 631 = 115059512010

Therefore, the lowest common multiple of 745,678,722,631 is 115059512010.

LCM Formula to Find Lowest Common Multiple of 745,678,722,631

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.

745 x 678 x 722 x 631 = 230119024020

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.

745 : 1, 5, 149, 745

678 : 1, 2, 3, 6, 113, 226, 339, 678

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

631 : 1, 631

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,678,722,631, is 1.

Now, the common factors can be found like this.

745:5x 149

678:2x 3x 113

722:2x 19x 19

631:631

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 = 230119024020/(1x2)

LCM = 230119024020/2

LCM = 115059512010

Thus, we can understand that the LCM of 745,678,722,631 is 115059512010.
