Given numbers are 686, 265, 223, 245

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(686, 265) = 181790

GCD(686, 265) = ( 686 x 265 ) / 181790

= 686 / 265

= 686

Step2:

LCM(1, 223) = 223

GCD(1, 223) = ( 1 x 223 ) / 223

= 1 / 223

= 1

Step3:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

So, Greatest Common Divisor of 686, 265, 223, 245 is 1
