GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 428) = 122836
GCD(287, 428) = ( 287 x 428 ) / 122836
= 287 / 428
= 287
Step2:
LCM(1, 608) = 608
GCD(1, 608) = ( 1 x 608 ) / 608
= 1 / 608
= 1
Step3:
LCM(1, 969) = 969
GCD(1, 969) = ( 1 x 969 ) / 969
= 1 / 969
= 1
So, Greatest Common Divisor of 287, 428, 608, 969 is 1
