Given numbers are 420, 669, 191, 986

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

Apply this formula for all numbers.

Step1:

LCM(420, 669) = 93660

GCD(420, 669) = ( 420 x 669 ) / 93660

= 420 / 669

= 420

Step2:

LCM(3, 191) = 573

GCD(3, 191) = ( 3 x 191 ) / 573

= 3 / 191

= 3

Step3:

LCM(1, 986) = 986

GCD(1, 986) = ( 1 x 986 ) / 986

= 1 / 986

= 1

So, Greatest Common Divisor of 420, 669, 191, 986 is 1
