Given numbers are 978, 576, 787, 872

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

Apply this formula for all numbers.

Step1:

LCM(978, 576) = 93888

GCD(978, 576) = ( 978 x 576 ) / 93888

= 978 / 576

= 978

Step2:

LCM(6, 787) = 4722

GCD(6, 787) = ( 6 x 787 ) / 4722

= 6 / 787

= 6

Step3:

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

= 1 / 872

= 1

So, Greatest Common Divisor of 978, 576, 787, 872 is 1
