Given numbers are 921, 822, 570, 978

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

Apply this formula for all numbers.

Step1:

LCM(921, 822) = 252354

GCD(921, 822) = ( 921 x 822 ) / 252354

= 921 / 822

= 921

Step2:

LCM(3, 570) = 570

GCD(3, 570) = ( 3 x 570 ) / 570

= 3 / 570

= 3

Step3:

LCM(3, 978) = 978

GCD(3, 978) = ( 3 x 978 ) / 978

= 3 / 978

= 3

So, Greatest Common Divisor of 921, 822, 570, 978 is 3
