Calculate the LCM of 843,393,109,721

Given numbers are 843,393,109,721

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

The LCM of 843,393,109,721 is 8678819037.

Find LCM of 843,393,109,721 with Prime Factorization


3 843, 393, 109, 721
281, 131, 109, 721

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

3 x 281 x 131 x 109 x 721 = 8678819037

Therefore, the lowest common multiple of 843,393,109,721 is 8678819037.

LCM Formula to Find Lowest Common Multiple of 843,393,109,721

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.

843 x 393 x 109 x 721 = 26036457111

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.

843 : 1, 3, 281, 843

393 : 1, 3, 131, 393

109 : 1, 109

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,393,109,721, is 1.

Now, the common factors can be found like this.

843:3x 281

393:3x 131

109:109

721:7x 103

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

3 = 3

Therefore, the value for common factors is 3.

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 = 26036457111/(1x3)

LCM = 26036457111/3

LCM = 8678819037

Thus, we can understand that the LCM of 843,393,109,721 is 8678819037.
