Given numbers are 563,187,691,847,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 563,187,691,847,221 is 72821920171.
Find LCM of 563,187,691,847,221 with Prime Factorization
| 11 | 563, 187, 691, 847, 221 |
| 17 | 563, 17, 691, 77, 221 |
| 563, 1, 691, 77, 13 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 563 x 1 x 691 x 77 x 13 = 72821920171
Therefore, the lowest common multiple of 563,187,691,847,221 is 72821920171.
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.
563 x 187 x 691 x 847 x 221 = 13617699071977
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.
563 : 1, 563
187 : 1, 11, 17, 187
691 : 1, 691
847 : 1, 7, 11, 77, 121, 847
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 563,187,691,847,221, is 1.
Now, the common factors can be found like this.
563:563
187:11x 17
691:691
847:7x 11x 11
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 17 = 187
Therefore, the value for common factors is 187.
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 = 13617699071977/(1x187)
LCM = 13617699071977/187
LCM = 72821920171
Thus, we can understand that the LCM of 563,187,691,847,221 is 72821920171.
