Given numbers are 821,299,988,987

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

The LCM of 821,299,988,987 is 18413870748.

Find LCM of 821,299,988,987 with Prime Factorization

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

13 x 821 x 23 x 76 x 987 = 18413870748

Therefore, the lowest common multiple of 821,299,988,987 is 18413870748.

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.

821 x 299 x 988 x 987 = 239380319724

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.

821 : 1, 821

299 : 1, 13, 23, 299

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

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,299,988,987, is 1.

Now, the common factors can be found like this.

821:821

299:13x 23

988:2x 2x 13x 19

987:3x 7x 47

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

13 = 13

Therefore, the value for common factors is 13.

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 = 239380319724/(1x13)

LCM = 239380319724/13

LCM = 18413870748

Thus, we can understand that the LCM of 821,299,988,987 is 18413870748.
