The LCM of 489,897,791,842 is 97379742642.

Find LCM of 489,897,791,842 with Prime Factorization


3 489, 897, 791, 842
163, 299, 791, 842

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

3 x 163 x 299 x 791 x 842 = 97379742642

Therefore, the lowest common multiple of 489,897,791,842 is 97379742642.

LCM Formula to Find Lowest Common Multiple of 489,897,791,842

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 897 x 791 x 842 = 292139227926

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

897 : 1, 3, 13, 23, 39, 69, 299, 897

791 : 1, 7, 113, 791

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,897,791,842, is 1.

Now, the common factors can be found like this.

489:3x 163

897:3x 13x 23

791:7x 113

842:2x 421

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 = 292139227926/(1x3)

LCM = 292139227926/3

LCM = 97379742642

Thus, we can understand that the LCM of 489,897,791,842 is 97379742642.
