Calculate the LCM of 721,993,188,442

Given numbers are 721,993,188,442

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

The LCM of 721,993,188,442 is 29746415244.

Find LCM of 721,993,188,442 with Prime Factorization


2 721, 993, 188, 442
721, 993, 94, 221

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

2 x 721 x 993 x 94 x 221 = 29746415244

Therefore, the lowest common multiple of 721,993,188,442 is 29746415244.

LCM Formula to Find Lowest Common Multiple of 721,993,188,442

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 993 x 188 x 442 = 59492830488

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

993 : 1, 3, 331, 993

188 : 1, 2, 4, 47, 94, 188

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,993,188,442, is 1.

Now, the common factors can be found like this.

721:7x 103

993:3x 331

188:2x 2x 47

442:2x 13x 17

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 = 59492830488/(1x2)

LCM = 59492830488/2

LCM = 29746415244

Thus, we can understand that the LCM of 721,993,188,442 is 29746415244.
