GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 153) = 50337
GCD(987, 153) = ( 987 x 153 ) / 50337
= 987 / 153
= 987
Step2:
LCM(3, 752) = 2256
GCD(3, 752) = ( 3 x 752 ) / 2256
= 3 / 752
= 3
Step3:
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
= 1 / 785
= 1
So, Greatest Common Divisor of 987, 153, 752, 785 is 1
