Given numbers are 660, 649, 778, 269

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

Apply this formula for all numbers.

Step1:

LCM(660, 649) = 38940

GCD(660, 649) = ( 660 x 649 ) / 38940

= 660 / 649

= 660

Step2:

LCM(11, 778) = 8558

GCD(11, 778) = ( 11 x 778 ) / 8558

= 11 / 778

= 11

Step3:

LCM(1, 269) = 269

GCD(1, 269) = ( 1 x 269 ) / 269

= 1 / 269

= 1

So, Greatest Common Divisor of 660, 649, 778, 269 is 1
