Given numbers are 278, 978, 272, 697

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

Apply this formula for all numbers.

Step1:

LCM(278, 978) = 135942

GCD(278, 978) = ( 278 x 978 ) / 135942

= 278 / 978

= 278

Step2:

LCM(2, 272) = 272

GCD(2, 272) = ( 2 x 272 ) / 272

= 2 / 272

= 2

Step3:

LCM(2, 697) = 1394

GCD(2, 697) = ( 2 x 697 ) / 1394

= 2 / 697

= 2

So, Greatest Common Divisor of 278, 978, 272, 697 is 1
