Given numbers are 129, 989, 180, 272
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(129, 989) = 2967
GCD(129, 989) = ( 129 x 989 ) / 2967
= 129 / 989
= 129
Step2:
LCM(43, 180) = 7740
GCD(43, 180) = ( 43 x 180 ) / 7740
= 43 / 180
= 43
Step3:
LCM(1, 272) = 272
GCD(1, 272) = ( 1 x 272 ) / 272
= 1 / 272
= 1
So, Greatest Common Divisor of 129, 989, 180, 272 is 1
