Given numbers are 871,860,457,221,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 871,860,457,221,847 is 4929071727580.
Find LCM of 871,860,457,221,847 with Prime Factorization
13 | 871, 860, 457, 221, 847 |
67, 860, 457, 17, 847 |
Multiply the prime numbers at the bottom and the left side.
13 x 67 x 860 x 457 x 17 x 847 = 4929071727580
Therefore, the lowest common multiple of 871,860,457,221,847 is 4929071727580.
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.
871 x 860 x 457 x 221 x 847 = 64077932458540
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.
871 : 1, 13, 67, 871
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
457 : 1, 457
221 : 1, 13, 17, 221
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,860,457,221,847, is 1.
Now, the common factors can be found like this.
871:13x 67
860:2x 2x 5x 43
457:457
221:13x 17
847:7x 11x 11
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 = 64077932458540/(1x13)
LCM = 64077932458540/13
LCM = 4929071727580
Thus, we can understand that the LCM of 871,860,457,221,847 is 4929071727580.
