Calculate the LCM of 772,810,923,721

Given numbers are 772,810,923,721

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

The LCM of 772,810,923,721 is 208069914780.

Find LCM of 772,810,923,721 with Prime Factorization


2 772, 810, 923, 721
386, 405, 923, 721

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

2 x 386 x 405 x 923 x 721 = 208069914780

Therefore, the lowest common multiple of 772,810,923,721 is 208069914780.

LCM Formula to Find Lowest Common Multiple of 772,810,923,721

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.

772 x 810 x 923 x 721 = 416139829560

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.

772 : 1, 2, 4, 193, 386, 772

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

923 : 1, 13, 71, 923

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,810,923,721, is 1.

Now, the common factors can be found like this.

772:2x 2x 193

810:2x 3x 3x 3x 3x 5

923:13x 71

721:7x 103

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 = 416139829560/(1x2)

LCM = 416139829560/2

LCM = 208069914780

Thus, we can understand that the LCM of 772,810,923,721 is 208069914780.
