Given numbers are 686, 569, 404, 281
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 569) = 390334
GCD(686, 569) = ( 686 x 569 ) / 390334
= 686 / 569
= 686
Step2:
LCM(1, 404) = 404
GCD(1, 404) = ( 1 x 404 ) / 404
= 1 / 404
= 1
Step3:
LCM(1, 281) = 281
GCD(1, 281) = ( 1 x 281 ) / 281
= 1 / 281
= 1
So, Greatest Common Divisor of 686, 569, 404, 281 is 1
