GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(772, 975) = 752700
GCD(772, 975) = ( 772 x 975 ) / 752700
= 772 / 975
= 772
Step2:
LCM(1, 808) = 808
GCD(1, 808) = ( 1 x 808 ) / 808
= 1 / 808
= 1
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 772, 975, 808, 455 is 1
