Calculate the LCM of 871,990,287,322

Given numbers are 871,990,287,322

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

The LCM of 871,990,287,322 is 5691976290.

Find LCM of 871,990,287,322 with Prime Factorization


2 871, 990, 287, 322
7 871, 495, 287, 161
871, 495, 41, 23

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

2 x 7 x 871 x 495 x 41 x 23 = 5691976290

Therefore, the lowest common multiple of 871,990,287,322 is 5691976290.

LCM Formula to Find Lowest Common Multiple of 871,990,287,322

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 990 x 287 x 322 = 79687668060

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

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

287 : 1, 7, 41, 287

322 : 1, 2, 7, 14, 23, 46, 161, 322

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,990,287,322, is 1.

Now, the common factors can be found like this.

871:13x 67

990:2x 3x 3x 5x 11

287:7x 41

322:2x 7x 23

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 79687668060/(1x14)

LCM = 79687668060/14

LCM = 5691976290

Thus, we can understand that the LCM of 871,990,287,322 is 5691976290.
