Given numbers are 171, 978, 816, 662

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, 816) = 816

GCD(3, 816) = ( 3 x 816 ) / 816

= 3 / 816

= 3

Step3:

LCM(3, 662) = 1986

GCD(3, 662) = ( 3 x 662 ) / 1986

= 3 / 662

= 3

So, Greatest Common Divisor of 171, 978, 816, 662 is 1
