Given numbers are 369, 981, 690, 779

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

Apply this formula for all numbers.

Step1:

LCM(369, 981) = 40221

GCD(369, 981) = ( 369 x 981 ) / 40221

= 369 / 981

= 369

Step2:

LCM(9, 690) = 2070

GCD(9, 690) = ( 9 x 690 ) / 2070

= 9 / 690

= 9

Step3:

LCM(3, 779) = 2337

GCD(3, 779) = ( 3 x 779 ) / 2337

= 3 / 779

= 3

So, Greatest Common Divisor of 369, 981, 690, 779 is 1
