Given numbers are 161, 145, 663, 341
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 145) = 23345
GCD(161, 145) = ( 161 x 145 ) / 23345
= 161 / 145
= 161
Step2:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
Step3:
LCM(1, 341) = 341
GCD(1, 341) = ( 1 x 341 ) / 341
= 1 / 341
= 1
So, Greatest Common Divisor of 161, 145, 663, 341 is 1
