Find LCM of 980,455,923,871,383 with Prime Factorization
| 5 | 980, 455, 923, 871, 383 |
| 7 | 196, 91, 923, 871, 383 |
| 13 | 28, 13, 923, 871, 383 |
| 28, 1, 71, 67, 383 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 13 x 28 x 1 x 71 x 67 x 383 = 23211400940
Therefore, the lowest common multiple of 980,455,923,871,383 is 23211400940.
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.
980 x 455 x 923 x 871 x 383 = 137295436560100
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
455 : 1, 5, 7, 13, 35, 65, 91, 455
923 : 1, 13, 71, 923
871 : 1, 13, 67, 871
383 : 1, 383
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,455,923,871,383, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
455:5x 7x 13
923:13x 71
871:13x 67
383:383
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 13x 13 = 5915
Therefore, the value for common factors is 5915.
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 = 137295436560100/(1x5915)
LCM = 137295436560100/5915
LCM = 23211400940
Thus, we can understand that the LCM of 980,455,923,871,383 is 23211400940.
