Calculate the LCM of 775,124,988,881

Given numbers are 775,124,988,881

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

The LCM of 775,124,988,881 is 674581700.

Find LCM of 775,124,988,881 with Prime Factorization


2 775, 124, 988, 881
2 775, 62, 494, 881
31 775, 31, 247, 881
25, 1, 247, 881

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

2 x 2 x 31 x 25 x 1 x 247 x 881 = 674581700

Therefore, the lowest common multiple of 775,124,988,881 is 674581700.

LCM Formula to Find Lowest Common Multiple of 775,124,988,881

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.

775 x 124 x 988 x 881 = 83648130800

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.

775 : 1, 5, 25, 31, 155, 775

124 : 1, 2, 4, 31, 62, 124

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

881 : 1, 881

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,124,988,881, is 1.

Now, the common factors can be found like this.

775:5x 5x 31

124:2x 2x 31

988:2x 2x 13x 19

881:881

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 31 = 124

Therefore, the value for common factors is 124.

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 = 83648130800/(1x124)

LCM = 83648130800/124

LCM = 674581700

Thus, we can understand that the LCM of 775,124,988,881 is 674581700.
