The LCM of 742,682,489,489 is 123727758.

Find LCM of 742,682,489,489 with Prime Factorization


2 742, 682, 489, 489
3 371, 341, 489, 489
163 371, 341, 163, 163
371, 341, 1, 1

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

2 x 3 x 163 x 371 x 341 x 1 x 1 = 123727758

Therefore, the lowest common multiple of 742,682,489,489 is 123727758.

LCM Formula to Find Lowest Common Multiple of 742,682,489,489

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.

742 x 682 x 489 x 489 = 121005747324

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.

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

682 : 1, 2, 11, 22, 31, 62, 341, 682

489 : 1, 3, 163, 489

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,682,489,489, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

682:2x 11x 31

489:3x 163

489:3x 163

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

2x 3x 163 = 978

Therefore, the value for common factors is 978.

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 = 121005747324/(1x978)

LCM = 121005747324/978

LCM = 123727758

Thus, we can understand that the LCM of 742,682,489,489 is 123727758.
