Calculate the LCM of 890,871,878,689

Given numbers are 890,871,878,689

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

The LCM of 890,871,878,689 is 18036345730.

Find LCM of 890,871,878,689 with Prime Factorization


2 890, 871, 878, 689
13 445, 871, 439, 689
445, 67, 439, 53

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

2 x 13 x 445 x 67 x 439 x 53 = 18036345730

Therefore, the lowest common multiple of 890,871,878,689 is 18036345730.

LCM Formula to Find Lowest Common Multiple of 890,871,878,689

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.

890 x 871 x 878 x 689 = 468944988980

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.

890 : 1, 2, 5, 10, 89, 178, 445, 890

871 : 1, 13, 67, 871

878 : 1, 2, 439, 878

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,871,878,689, is 1.

Now, the common factors can be found like this.

890:2x 5x 89

871:13x 67

878:2x 439

689:13x 53

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 468944988980/(1x26)

LCM = 468944988980/26

LCM = 18036345730

Thus, we can understand that the LCM of 890,871,878,689 is 18036345730.
