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 639 are 3 x 3 x 71
Prime factors of 124 are 2 x 2 x 31
Prime factors of 565 are 5 x 113
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 810, 639, 124, 565
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 639) = 57510
GCD(810, 639) = ( 810 x 639 ) / 57510
= 810 / 639
= 810
Step2:
LCM(9, 124) = 1116
GCD(9, 124) = ( 9 x 124 ) / 1116
= 9 / 124
= 9
Step3:
LCM(1, 565) = 565
GCD(1, 565) = ( 1 x 565 ) / 565
= 1 / 565
= 1
So, Greatest Common Divisor of 810, 639, 124, 565 is 1
