Find LCM of 504,576,973,978,721 with Prime Factorization
| 2 | 504, 576, 973, 978, 721 |
| 2 | 252, 288, 973, 489, 721 |
| 2 | 126, 144, 973, 489, 721 |
| 3 | 63, 72, 973, 489, 721 |
| 3 | 21, 24, 973, 163, 721 |
| 7 | 7, 8, 973, 163, 721 |
| 1, 8, 139, 163, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 7 x 1 x 8 x 139 x 163 x 103 = 9409361472
Therefore, the lowest common multiple of 504,576,973,978,721 is 9409361472.
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.
504 x 576 x 973 x 978 x 721 = 199177363639296
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.
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
973 : 1, 7, 139, 973
978 : 1, 2, 3, 6, 163, 326, 489, 978
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 504,576,973,978,721, is 1.
Now, the common factors can be found like this.
504:2x 2x 2x 3x 3x 7
576:2x 2x 2x 2x 2x 2x 3x 3
973:7x 139
978:2x 3x 163
721:7x 103
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 2x 2x 3x 3x 3x 7x 7 = 21168
Therefore, the value for common factors is 21168.
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 = 199177363639296/(1x21168)
LCM = 199177363639296/21168
LCM = 9409361472
Thus, we can understand that the LCM of 504,576,973,978,721 is 9409361472.
