Given numbers are 686, 334, 161, 475
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 334) = 114562
GCD(686, 334) = ( 686 x 334 ) / 114562
= 686 / 334
= 686
Step2:
LCM(2, 161) = 322
GCD(2, 161) = ( 2 x 161 ) / 322
= 2 / 161
= 2
Step3:
LCM(1, 475) = 475
GCD(1, 475) = ( 1 x 475 ) / 475
= 1 / 475
= 1
So, Greatest Common Divisor of 686, 334, 161, 475 is 1
