Calculate the LCM of 752,721,556,412

Given numbers are 752,721,556,412

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

The LCM of 752,721,556,412 is 75364688.

Find LCM of 752,721,556,412 with Prime Factorization


2 752, 721, 556, 412
2 376, 721, 278, 206
103 188, 721, 139, 103
188, 7, 139, 1

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

2 x 2 x 103 x 188 x 7 x 139 x 1 = 75364688

Therefore, the lowest common multiple of 752,721,556,412 is 75364688.

LCM Formula to Find Lowest Common Multiple of 752,721,556,412

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.

752 x 721 x 556 x 412 = 124201005824

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.

752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752

721 : 1, 7, 103, 721

556 : 1, 2, 4, 139, 278, 556

412 : 1, 2, 4, 103, 206, 412

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 752,721,556,412, is 1.

Now, the common factors can be found like this.

752:2x 2x 2x 2x 47

721:7x 103

556:2x 2x 139

412:2x 2x 103

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 2x 2x 103 = 1648

Therefore, the value for common factors is 1648.

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 = 124201005824/(1x1648)

LCM = 124201005824/1648

LCM = 75364688

Thus, we can understand that the LCM of 752,721,556,412 is 75364688.
