Given numbers are 978, 945, 22, 239

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

Apply this formula for all numbers.

Step1:

LCM(978, 945) = 308070

GCD(978, 945) = ( 978 x 945 ) / 308070

= 978 / 945

= 978

Step2:

LCM(3, 22) = 66

GCD(3, 22) = ( 3 x 22 ) / 66

= 3 / 22

= 3

Step3:

LCM(1, 239) = 239

GCD(1, 239) = ( 1 x 239 ) / 239

= 1 / 239

= 1

So, Greatest Common Divisor of 978, 945, 22, 239 is 1
