Find LCM of 987,602,290,813,609 with Prime Factorization
| 2 | 987, 602, 290, 813, 609 |
| 3 | 987, 301, 145, 813, 609 |
| 7 | 329, 301, 145, 271, 203 |
| 29 | 47, 43, 145, 271, 29 |
| 47, 43, 5, 271, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 29 x 47 x 43 x 5 x 271 x 1 = 3335438190
Therefore, the lowest common multiple of 987,602,290,813,609 is 3335438190.
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 602 x 290 x 813 x 609 = 85313838023820
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
602 : 1, 2, 7, 14, 43, 86, 301, 602
290 : 1, 2, 5, 10, 29, 58, 145, 290
813 : 1, 3, 271, 813
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 987,602,290,813,609, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
602:2x 7x 43
290:2x 5x 29
813:3x 271
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 3x 3x 7x 7x 29 = 25578
Therefore, the value for common factors is 25578.
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 = 85313838023820/(1x25578)
LCM = 85313838023820/25578
LCM = 3335438190
Thus, we can understand that the LCM of 987,602,290,813,609 is 3335438190.
