GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(128, 988) = 31616
GCD(128, 988) = ( 128 x 988 ) / 31616
= 128 / 988
= 128
Step2:
LCM(4, 511) = 2044
GCD(4, 511) = ( 4 x 511 ) / 2044
= 4 / 511
= 4
Step3:
LCM(1, 989) = 989
GCD(1, 989) = ( 1 x 989 ) / 989
= 1 / 989
= 1
So, Greatest Common Divisor of 128, 988, 511, 989 is 1
