Find LCM of 845,300,980,885,987 with Prime Factorization
| 2 | 845, 300, 980, 885, 987 |
| 2 | 845, 150, 490, 885, 987 |
| 3 | 845, 75, 245, 885, 987 |
| 5 | 845, 25, 245, 295, 329 |
| 7 | 169, 5, 49, 59, 329 |
| 169, 5, 7, 59, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 169 x 5 x 7 x 59 x 47 = 6888963900
Therefore, the lowest common multiple of 845,300,980,885,987 is 6888963900.
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.
845 x 300 x 980 x 885 x 987 = 217002362850000
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.
845 : 1, 5, 13, 65, 169, 845
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
885 : 1, 3, 5, 15, 59, 177, 295, 885
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,300,980,885,987, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
300:2x 2x 3x 5x 5
980:2x 2x 5x 7x 7
885:3x 5x 59
987:3x 7x 47
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 3x 3x 5x 5x 5x 7 = 31500
Therefore, the value for common factors is 31500.
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 = 217002362850000/(1x31500)
LCM = 217002362850000/31500
LCM = 6888963900
Thus, we can understand that the LCM of 845,300,980,885,987 is 6888963900.
