Given numbers are 217, 257, 181, 695
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 257) = 55769
GCD(217, 257) = ( 217 x 257 ) / 55769
= 217 / 257
= 217
Step2:
LCM(1, 181) = 181
GCD(1, 181) = ( 1 x 181 ) / 181
= 1 / 181
= 1
Step3:
LCM(1, 695) = 695
GCD(1, 695) = ( 1 x 695 ) / 695
= 1 / 695
= 1
So, Greatest Common Divisor of 217, 257, 181, 695 is 1
