Given numbers are 205, 821, 791, 626
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(205, 821) = 168305
GCD(205, 821) = ( 205 x 821 ) / 168305
= 205 / 821
= 205
Step2:
LCM(1, 791) = 791
GCD(1, 791) = ( 1 x 791 ) / 791
= 1 / 791
= 1
Step3:
LCM(1, 626) = 626
GCD(1, 626) = ( 1 x 626 ) / 626
= 1 / 626
= 1
So, Greatest Common Divisor of 205, 821, 791, 626 is 1
