Given numbers are 685, 133, 427, 193
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 133) = 91105
GCD(685, 133) = ( 685 x 133 ) / 91105
= 685 / 133
= 685
Step2:
LCM(1, 427) = 427
GCD(1, 427) = ( 1 x 427 ) / 427
= 1 / 427
= 1
Step3:
LCM(1, 193) = 193
GCD(1, 193) = ( 1 x 193 ) / 193
= 1 / 193
= 1
So, Greatest Common Divisor of 685, 133, 427, 193 is 1
