Given numbers are 810, 221, 652, 805
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 221 are 13 x 17
Prime factors of 652 are 2 x 2 x 163
Prime factors of 805 are 5 x 7 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 810, 221, 652, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 221) = 179010
GCD(810, 221) = ( 810 x 221 ) / 179010
= 810 / 221
= 810
Step2:
LCM(1, 652) = 652
GCD(1, 652) = ( 1 x 652 ) / 652
= 1 / 652
= 1
Step3:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
So, Greatest Common Divisor of 810, 221, 652, 805 is 1
