Given numbers are 427, 978, 823, 657

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

Apply this formula for all numbers.

Step1:

LCM(427, 978) = 417606

GCD(427, 978) = ( 427 x 978 ) / 417606

= 427 / 978

= 427

Step2:

LCM(1, 823) = 823

GCD(1, 823) = ( 1 x 823 ) / 823

= 1 / 823

= 1

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 427, 978, 823, 657 is 1
