Given numbers are 185, 686, 118, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(185, 686) = 126910
GCD(185, 686) = ( 185 x 686 ) / 126910
= 185 / 686
= 185
Step2:
LCM(1, 118) = 118
GCD(1, 118) = ( 1 x 118 ) / 118
= 1 / 118
= 1
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 185, 686, 118, 649 is 1
