Given numbers are 168, 978, 534, 121

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

Apply this formula for all numbers.

Step1:

LCM(168, 978) = 27384

GCD(168, 978) = ( 168 x 978 ) / 27384

= 168 / 978

= 168

Step2:

LCM(6, 534) = 534

GCD(6, 534) = ( 6 x 534 ) / 534

= 6 / 534

= 6

Step3:

LCM(6, 121) = 726

GCD(6, 121) = ( 6 x 121 ) / 726

= 6 / 121

= 6

So, Greatest Common Divisor of 168, 978, 534, 121 is 1
