Given numbers are 353, 491, 686, 205
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(353, 491) = 173323
GCD(353, 491) = ( 353 x 491 ) / 173323
= 353 / 491
= 353
Step2:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
Step3:
LCM(1, 205) = 205
GCD(1, 205) = ( 1 x 205 ) / 205
= 1 / 205
= 1
So, Greatest Common Divisor of 353, 491, 686, 205 is 1
