Given numbers are 658, 205, 195, 161
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 205) = 134890
GCD(658, 205) = ( 658 x 205 ) / 134890
= 658 / 205
= 658
Step2:
LCM(1, 195) = 195
GCD(1, 195) = ( 1 x 195 ) / 195
= 1 / 195
= 1
Step3:
LCM(1, 161) = 161
GCD(1, 161) = ( 1 x 161 ) / 161
= 1 / 161
= 1
So, Greatest Common Divisor of 658, 205, 195, 161 is 1
