Given numbers are 978, 292, 430, 949

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

Apply this formula for all numbers.

Step1:

LCM(978, 292) = 142788

GCD(978, 292) = ( 978 x 292 ) / 142788

= 978 / 292

= 978

Step2:

LCM(2, 430) = 430

GCD(2, 430) = ( 2 x 430 ) / 430

= 2 / 430

= 2

Step3:

LCM(2, 949) = 1898

GCD(2, 949) = ( 2 x 949 ) / 1898

= 2 / 949

= 2

So, Greatest Common Divisor of 978, 292, 430, 949 is 1
