The LCM of 489,389,742,791 is 15949269966.

Find LCM of 489,389,742,791 with Prime Factorization


7 489, 389, 742, 791
489, 389, 106, 113

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

7 x 489 x 389 x 106 x 113 = 15949269966

Therefore, the lowest common multiple of 489,389,742,791 is 15949269966.

LCM Formula to Find Lowest Common Multiple of 489,389,742,791

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.

489 x 389 x 742 x 791 = 111644889762

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.

489 : 1, 3, 163, 489

389 : 1, 389

742 : 1, 2, 7, 14, 53, 106, 371, 742

791 : 1, 7, 113, 791

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,389,742,791, is 1.

Now, the common factors can be found like this.

489:3x 163

389:389

742:2x 7x 53

791:7x 113

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

7 = 7

Therefore, the value for common factors is 7.

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 = 111644889762/(1x7)

LCM = 111644889762/7

LCM = 15949269966

Thus, we can understand that the LCM of 489,389,742,791 is 15949269966.
