Calculate the LCM of 721,710,537,556

Given numbers are 721,710,537,556

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

The LCM of 721,710,537,556 is 76420996260.

Find LCM of 721,710,537,556 with Prime Factorization


2 721, 710, 537, 556
721, 355, 537, 278

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

2 x 721 x 355 x 537 x 278 = 76420996260

Therefore, the lowest common multiple of 721,710,537,556 is 76420996260.

LCM Formula to Find Lowest Common Multiple of 721,710,537,556

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.

721 x 710 x 537 x 556 = 152841992520

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.

721 : 1, 7, 103, 721

710 : 1, 2, 5, 10, 71, 142, 355, 710

537 : 1, 3, 179, 537

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,710,537,556, is 1.

Now, the common factors can be found like this.

721:7x 103

710:2x 5x 71

537:3x 179

556:2x 2x 139

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 = 152841992520/(1x2)

LCM = 152841992520/2

LCM = 76420996260

Thus, we can understand that the LCM of 721,710,537,556 is 76420996260.
