Given numbers are 161, 987, 103, 487
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 987) = 22701
GCD(161, 987) = ( 161 x 987 ) / 22701
= 161 / 987
= 161
Step2:
LCM(7, 103) = 721
GCD(7, 103) = ( 7 x 103 ) / 721
= 7 / 103
= 7
Step3:
LCM(1, 487) = 487
GCD(1, 487) = ( 1 x 487 ) / 487
= 1 / 487
= 1
So, Greatest Common Divisor of 161, 987, 103, 487 is 1
