Given numbers are 813, 420, 840, 595
The list of prime factors of all numbers are
Prime factors of 813 are 3 x 271
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
Prime factors of 595 are 5 x 7 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 813, 420, 840, 595
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 420) = 113820
GCD(813, 420) = ( 813 x 420 ) / 113820
= 813 / 420
= 813
Step2:
LCM(3, 840) = 840
GCD(3, 840) = ( 3 x 840 ) / 840
= 3 / 840
= 3
Step3:
LCM(3, 595) = 1785
GCD(3, 595) = ( 3 x 595 ) / 1785
= 3 / 595
= 3
So, Greatest Common Divisor of 813, 420, 840, 595 is 1
