Calculate the LCM of 890,561,866,649

Given numbers are 890,561,866,649

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

The LCM of 890,561,866,649 is 12755361630.

Find LCM of 890,561,866,649 with Prime Factorization


2 890, 561, 866, 649
11 445, 561, 433, 649
445, 51, 433, 59

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

2 x 11 x 445 x 51 x 433 x 59 = 12755361630

Therefore, the lowest common multiple of 890,561,866,649 is 12755361630.

LCM Formula to Find Lowest Common Multiple of 890,561,866,649

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 561 x 866 x 649 = 280617955860

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

561 : 1, 3, 11, 17, 33, 51, 187, 561

866 : 1, 2, 433, 866

649 : 1, 11, 59, 649

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,561,866,649, is 1.

Now, the common factors can be found like this.

890:2x 5x 89

561:3x 11x 17

866:2x 433

649:11x 59

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 280617955860/(1x22)

LCM = 280617955860/22

LCM = 12755361630

Thus, we can understand that the LCM of 890,561,866,649 is 12755361630.
