Calculate the LCM of 990,998,877,738

Given numbers are 990,998,877,738

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

The LCM of 990,998,877,738 is 17763117570.

Find LCM of 990,998,877,738 with Prime Factorization


2 990, 998, 877, 738
3 495, 499, 877, 369
3 165, 499, 877, 123
55, 499, 877, 41

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

2 x 3 x 3 x 55 x 499 x 877 x 41 = 17763117570

Therefore, the lowest common multiple of 990,998,877,738 is 17763117570.

LCM Formula to Find Lowest Common Multiple of 990,998,877,738

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.

990 x 998 x 877 x 738 = 639472232520

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.

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

998 : 1, 2, 499, 998

877 : 1, 877

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,998,877,738, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

998:2x 499

877:877

738:2x 3x 3x 41

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

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 639472232520/(1x36)

LCM = 639472232520/36

LCM = 17763117570

Thus, we can understand that the LCM of 990,998,877,738 is 17763117570.
