Given numbers are 978, 278, 722, 975

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

Apply this formula for all numbers.

Step1:

LCM(978, 278) = 135942

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

= 978 / 278

= 978

Step2:

LCM(2, 722) = 722

GCD(2, 722) = ( 2 x 722 ) / 722

= 2 / 722

= 2

Step3:

LCM(2, 975) = 1950

GCD(2, 975) = ( 2 x 975 ) / 1950

= 2 / 975

= 2

So, Greatest Common Divisor of 978, 278, 722, 975 is 1
