Given numbers are 978, 771, 531, 887

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

Apply this formula for all numbers.

Step1:

LCM(978, 771) = 251346

GCD(978, 771) = ( 978 x 771 ) / 251346

= 978 / 771

= 978

Step2:

LCM(3, 531) = 531

GCD(3, 531) = ( 3 x 531 ) / 531

= 3 / 531

= 3

Step3:

LCM(3, 887) = 2661

GCD(3, 887) = ( 3 x 887 ) / 2661

= 3 / 887

= 3

So, Greatest Common Divisor of 978, 771, 531, 887 is 1
