Given numbers are 978, 664, 475, 835

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

Apply this formula for all numbers.

Step1:

LCM(978, 664) = 324696

GCD(978, 664) = ( 978 x 664 ) / 324696

= 978 / 664

= 978

Step2:

LCM(2, 475) = 950

GCD(2, 475) = ( 2 x 475 ) / 950

= 2 / 475

= 2

Step3:

LCM(1, 835) = 835

GCD(1, 835) = ( 1 x 835 ) / 835

= 1 / 835

= 1

So, Greatest Common Divisor of 978, 664, 475, 835 is 1
