Given numbers are 749, 178, 854, 981
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(749, 178) = 133322
GCD(749, 178) = ( 749 x 178 ) / 133322
= 749 / 178
= 749
Step2:
LCM(1, 854) = 854
GCD(1, 854) = ( 1 x 854 ) / 854
= 1 / 854
= 1
Step3:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
So, Greatest Common Divisor of 749, 178, 854, 981 is 1
