Calculate the LCM of 717,721,351,291

Given numbers are 717,721,351,291

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

The LCM of 717,721,351,291 is 5866944993.

Find LCM of 717,721,351,291 with Prime Factorization


3 717, 721, 351, 291
239, 721, 117, 97

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

3 x 239 x 721 x 117 x 97 = 5866944993

Therefore, the lowest common multiple of 717,721,351,291 is 5866944993.

LCM Formula to Find Lowest Common Multiple of 717,721,351,291

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.

717 x 721 x 351 x 291 = 52802504937

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.

717 : 1, 3, 239, 717

721 : 1, 7, 103, 721

351 : 1, 3, 9, 13, 27, 39, 117, 351

291 : 1, 3, 97, 291

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,721,351,291, is 1.

Now, the common factors can be found like this.

717:3x 239

721:7x 103

351:3x 3x 3x 13

291:3x 97

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 52802504937/(1x9)

LCM = 52802504937/9

LCM = 5866944993

Thus, we can understand that the LCM of 717,721,351,291 is 5866944993.
