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

Apply this formula for all numbers.

Step1:

LCM(828, 978) = 134964

GCD(828, 978) = ( 828 x 978 ) / 134964

= 828 / 978

= 828

Step2:

LCM(6, 530) = 1590

GCD(6, 530) = ( 6 x 530 ) / 1590

= 6 / 530

= 6

Step3:

LCM(2, 978) = 978

GCD(2, 978) = ( 2 x 978 ) / 978

= 2 / 978

= 2

So, Greatest Common Divisor of 828, 978, 530, 978 is 2
