Given numbers are 420, 978, 153, 268

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

Apply this formula for all numbers.

Step1:

LCM(420, 978) = 68460

GCD(420, 978) = ( 420 x 978 ) / 68460

= 420 / 978

= 420

Step2:

LCM(6, 153) = 306

GCD(6, 153) = ( 6 x 153 ) / 306

= 6 / 153

= 6

Step3:

LCM(3, 268) = 804

GCD(3, 268) = ( 3 x 268 ) / 804

= 3 / 268

= 3

So, Greatest Common Divisor of 420, 978, 153, 268 is 1
