Calculate the LCM of 793,987,987,890

Given numbers are 793,987,987,890

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

The LCM of 793,987,987,890 is 696594990.

Find LCM of 793,987,987,890 with Prime Factorization


3 793, 987, 987, 890
7 793, 329, 329, 890
47 793, 47, 47, 890
793, 1, 1, 890

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

3 x 7 x 47 x 793 x 1 x 1 x 890 = 696594990

Therefore, the lowest common multiple of 793,987,987,890 is 696594990.

LCM Formula to Find Lowest Common Multiple of 793,987,987,890

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.

793 x 987 x 987 x 890 = 687539255130

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.

793 : 1, 13, 61, 793

987 : 1, 3, 7, 21, 47, 141, 329, 987

987 : 1, 3, 7, 21, 47, 141, 329, 987

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 793,987,987,890, is 1.

Now, the common factors can be found like this.

793:13x 61

987:3x 7x 47

987:3x 7x 47

890:2x 5x 89

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

3x 7x 47 = 987

Therefore, the value for common factors is 987.

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 = 687539255130/(1x987)

LCM = 687539255130/987

LCM = 696594990

Thus, we can understand that the LCM of 793,987,987,890 is 696594990.
