Find LCM of 987,820,235,712,911 with Prime Factorization
| 2 | 987, 820, 235, 712, 911 |
| 2 | 987, 410, 235, 356, 911 |
| 5 | 987, 205, 235, 178, 911 |
| 47 | 987, 41, 47, 178, 911 |
| 21, 41, 1, 178, 911 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 47 x 21 x 41 x 1 x 178 x 911 = 131240955720
Therefore, the lowest common multiple of 987,820,235,712,911 is 131240955720.
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 820 x 235 x 712 x 911 = 123366498376800
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
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
235 : 1, 5, 47, 235
712 : 1, 2, 4, 8, 89, 178, 356, 712
911 : 1, 911
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,820,235,712,911, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
820:2x 2x 5x 41
235:5x 47
712:2x 2x 2x 89
911:911
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 47 = 940
Therefore, the value for common factors is 940.
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 = 123366498376800/(1x940)
LCM = 123366498376800/940
LCM = 131240955720
Thus, we can understand that the LCM of 987,820,235,712,911 is 131240955720.
