Given numbers are 662, 978, 66, 816

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

Apply this formula for all numbers.

Step1:

LCM(662, 978) = 323718

GCD(662, 978) = ( 662 x 978 ) / 323718

= 662 / 978

= 662

Step2:

LCM(2, 66) = 66

GCD(2, 66) = ( 2 x 66 ) / 66

= 2 / 66

= 2

Step3:

LCM(2, 816) = 816

GCD(2, 816) = ( 2 x 816 ) / 816

= 2 / 816

= 2

So, Greatest Common Divisor of 662, 978, 66, 816 is 2
