Calculate the LCM of 551,892,987,747

Given numbers are 551,892,987,747

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

The LCM of 551,892,987,747 is 120790548396.

Find LCM of 551,892,987,747 with Prime Factorization


3 551, 892, 987, 747
551, 892, 329, 249

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

3 x 551 x 892 x 329 x 249 = 120790548396

Therefore, the lowest common multiple of 551,892,987,747 is 120790548396.

LCM Formula to Find Lowest Common Multiple of 551,892,987,747

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.

551 x 892 x 987 x 747 = 362371645188

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.

551 : 1, 19, 29, 551

892 : 1, 2, 4, 223, 446, 892

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

747 : 1, 3, 9, 83, 249, 747

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,892,987,747, is 1.

Now, the common factors can be found like this.

551:19x 29

892:2x 2x 223

987:3x 7x 47

747:3x 3x 83

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

3 = 3

Therefore, the value for common factors is 3.

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 = 362371645188/(1x3)

LCM = 362371645188/3

LCM = 120790548396

Thus, we can understand that the LCM of 551,892,987,747 is 120790548396.
