Given numbers are 657, 963, 280, 340

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

Apply this formula for all numbers.

Step1:

LCM(657, 963) = 70299

GCD(657, 963) = ( 657 x 963 ) / 70299

= 657 / 963

= 657

Step2:

LCM(9, 280) = 2520

GCD(9, 280) = ( 9 x 280 ) / 2520

= 9 / 280

= 9

Step3:

LCM(1, 340) = 340

GCD(1, 340) = ( 1 x 340 ) / 340

= 1 / 340

= 1

So, Greatest Common Divisor of 657, 963, 280, 340 is 1
