Given numbers are 770, 942, 178, 989
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 942) = 362670
GCD(770, 942) = ( 770 x 942 ) / 362670
= 770 / 942
= 770
Step2:
LCM(2, 178) = 178
GCD(2, 178) = ( 2 x 178 ) / 178
= 2 / 178
= 2
Step3:
LCM(2, 989) = 1978
GCD(2, 989) = ( 2 x 989 ) / 1978
= 2 / 989
= 2
So, Greatest Common Divisor of 770, 942, 178, 989 is 1
