Given numbers are 278, 548, 920, 979

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

Apply this formula for all numbers.

Step1:

LCM(278, 548) = 76172

GCD(278, 548) = ( 278 x 548 ) / 76172

= 278 / 548

= 278

Step2:

LCM(2, 920) = 920

GCD(2, 920) = ( 2 x 920 ) / 920

= 2 / 920

= 2

Step3:

LCM(2, 979) = 1958

GCD(2, 979) = ( 2 x 979 ) / 1958

= 2 / 979

= 2

So, Greatest Common Divisor of 278, 548, 920, 979 is 1
