Given numbers are 897, 561, 389, 629
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(897, 561) = 167739
GCD(897, 561) = ( 897 x 561 ) / 167739
= 897 / 561
= 897
Step2:
LCM(3, 389) = 1167
GCD(3, 389) = ( 3 x 389 ) / 1167
= 3 / 389
= 3
Step3:
LCM(1, 629) = 629
GCD(1, 629) = ( 1 x 629 ) / 629
= 1 / 629
= 1
So, Greatest Common Divisor of 897, 561, 389, 629 is 1
