Given numbers are 168, 147, 778, 484

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

Apply this formula for all numbers.

Step1:

LCM(168, 147) = 1176

GCD(168, 147) = ( 168 x 147 ) / 1176

= 168 / 147

= 168

Step2:

LCM(21, 778) = 16338

GCD(21, 778) = ( 21 x 778 ) / 16338

= 21 / 778

= 21

Step3:

LCM(1, 484) = 484

GCD(1, 484) = ( 1 x 484 ) / 484

= 1 / 484

= 1

So, Greatest Common Divisor of 168, 147, 778, 484 is 1
