Given numbers are 685, 970, 304, 655

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

Apply this formula for all numbers.

Step1:

LCM(685, 970) = 132890

GCD(685, 970) = ( 685 x 970 ) / 132890

= 685 / 970

= 685

Step2:

LCM(5, 304) = 1520

GCD(5, 304) = ( 5 x 304 ) / 1520

= 5 / 304

= 5

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 685, 970, 304, 655 is 1
