Calculate the LCM of 778,242,939,972

Given numbers are 778,242,939,972

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

The LCM of 778,242,939,972 is 14320084284.

Find LCM of 778,242,939,972 with Prime Factorization


2 778, 242, 939, 972
3 389, 121, 939, 486
389, 121, 313, 162

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

2 x 3 x 389 x 121 x 313 x 162 = 14320084284

Therefore, the lowest common multiple of 778,242,939,972 is 14320084284.

LCM Formula to Find Lowest Common Multiple of 778,242,939,972

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.

778 x 242 x 939 x 972 = 171841011408

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.

778 : 1, 2, 389, 778

242 : 1, 2, 11, 22, 121, 242

939 : 1, 3, 313, 939

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,242,939,972, is 1.

Now, the common factors can be found like this.

778:2x 389

242:2x 11x 11

939:3x 313

972:2x 2x 3x 3x 3x 3x 3

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 3 = 12

Therefore, the value for common factors is 12.

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 = 171841011408/(1x12)

LCM = 171841011408/12

LCM = 14320084284

Thus, we can understand that the LCM of 778,242,939,972 is 14320084284.
