Calculate the LCM of 871,791,904,897

Given numbers are 871,791,904,897

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

The LCM of 871,791,904,897 is 380306472.

Find LCM of 871,791,904,897 with Prime Factorization


13 871, 791, 904, 897
113 67, 791, 904, 69
67, 7, 8, 69

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

13 x 113 x 67 x 7 x 8 x 69 = 380306472

Therefore, the lowest common multiple of 871,791,904,897 is 380306472.

LCM Formula to Find Lowest Common Multiple of 871,791,904,897

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.

871 x 791 x 904 x 897 = 558670207368

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.

871 : 1, 13, 67, 871

791 : 1, 7, 113, 791

904 : 1, 2, 4, 8, 113, 226, 452, 904

897 : 1, 3, 13, 23, 39, 69, 299, 897

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,791,904,897, is 1.

Now, the common factors can be found like this.

871:13x 67

791:7x 113

904:2x 2x 2x 113

897:3x 13x 23

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

13x 113 = 1469

Therefore, the value for common factors is 1469.

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 = 558670207368/(1x1469)

LCM = 558670207368/1469

LCM = 380306472

Thus, we can understand that the LCM of 871,791,904,897 is 380306472.
