Given numbers are 273, 978, 149, 980

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

Apply this formula for all numbers.

Step1:

LCM(273, 978) = 88998

GCD(273, 978) = ( 273 x 978 ) / 88998

= 273 / 978

= 273

Step2:

LCM(3, 149) = 447

GCD(3, 149) = ( 3 x 149 ) / 447

= 3 / 149

= 3

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 273, 978, 149, 980 is 1
