The LCM of 988,475,620,609 is 466311300.

Find LCM of 988,475,620,609 with Prime Factorization


2 988, 475, 620, 609
2 494, 475, 310, 609
5 247, 475, 155, 609
19 247, 95, 31, 609
13, 5, 31, 609

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

2 x 2 x 5 x 19 x 13 x 5 x 31 x 609 = 466311300

Therefore, the lowest common multiple of 988,475,620,609 is 466311300.

LCM Formula to Find Lowest Common Multiple of 988,475,620,609

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.

988 x 475 x 620 x 609 = 177198294000

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.

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

475 : 1, 5, 19, 25, 95, 475

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

609 : 1, 3, 7, 21, 29, 87, 203, 609

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,475,620,609, is 1.

Now, the common factors can be found like this.

988:2x 2x 13x 19

475:5x 5x 19

620:2x 2x 5x 31

609:3x 7x 29

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

2x 2x 5x 19 = 380

Therefore, the value for common factors is 380.

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 = 177198294000/(1x380)

LCM = 177198294000/380

LCM = 466311300

Thus, we can understand that the LCM of 988,475,620,609 is 466311300.
