The LCM of 987,791,378,449 is 901393542.

Find LCM of 987,791,378,449 with Prime Factorization


3 987, 791, 378, 449
7 329, 791, 126, 449
47, 113, 18, 449

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

3 x 7 x 47 x 113 x 18 x 449 = 901393542

Therefore, the lowest common multiple of 987,791,378,449 is 901393542.

LCM Formula to Find Lowest Common Multiple of 987,791,378,449

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.

987 x 791 x 378 x 449 = 132504850674

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.

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

791 : 1, 7, 113, 791

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

449 : 1, 449

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,791,378,449, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

791:7x 113

378:2x 3x 3x 3x 7

449:449

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 7 = 147

Therefore, the value for common factors is 147.

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 = 132504850674/(1x147)

LCM = 132504850674/147

LCM = 901393542

Thus, we can understand that the LCM of 987,791,378,449 is 901393542.
