Given numbers are 810, 811, 847, 666
The list of prime factors of all numbers are
Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5
Prime factors of 811 are 811
Prime factors of 847 are 7 x 11 x 11
Prime factors of 666 are 2 x 3 x 3 x 37
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 810, 811, 847, 666
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 811) = 656910
GCD(810, 811) = ( 810 x 811 ) / 656910
= 810 / 811
= 810
Step2:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
Step3:
LCM(1, 666) = 666
GCD(1, 666) = ( 1 x 666 ) / 666
= 1 / 666
= 1
So, Greatest Common Divisor of 810, 811, 847, 666 is 1
