GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(243, 987) = 79947
GCD(243, 987) = ( 243 x 987 ) / 79947
= 243 / 987
= 243
Step2:
LCM(3, 289) = 867
GCD(3, 289) = ( 3 x 289 ) / 867
= 3 / 289
= 3
Step3:
LCM(1, 452) = 452
GCD(1, 452) = ( 1 x 452 ) / 452
= 1 / 452
= 1
So, Greatest Common Divisor of 243, 987, 289, 452 is 1
