Given numbers are 171, 978, 854, 772

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

Apply this formula for all numbers.

Step1:

LCM(171, 978) = 55746

GCD(171, 978) = ( 171 x 978 ) / 55746

= 171 / 978

= 171

Step2:

LCM(3, 854) = 2562

GCD(3, 854) = ( 3 x 854 ) / 2562

= 3 / 854

= 3

Step3:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

So, Greatest Common Divisor of 171, 978, 854, 772 is 1
