Given numbers are 221,871,787,383
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,871,787,383 is 4463140747.
Find LCM of 221,871,787,383 with Prime Factorization
13 | 221, 871, 787, 383 |
17, 67, 787, 383 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 67 x 787 x 383 = 4463140747
Therefore, the lowest common multiple of 221,871,787,383 is 4463140747.
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.
221 x 871 x 787 x 383 = 58020829711
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.
221 : 1, 13, 17, 221
871 : 1, 13, 67, 871
787 : 1, 787
383 : 1, 383
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,871,787,383, is 1.
Now, the common factors can be found like this.
221:13x 17
871:13x 67
787:787
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.
13 = 13
Therefore, the value for common factors is 13.
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 = 58020829711/(1x13)
LCM = 58020829711/13
LCM = 4463140747
Thus, we can understand that the LCM of 221,871,787,383 is 4463140747.
