Given numbers are 822, 474, 197, 128

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

Apply this formula for all numbers.

Step1:

LCM(822, 474) = 64938

GCD(822, 474) = ( 822 x 474 ) / 64938

= 822 / 474

= 822

Step2:

LCM(6, 197) = 1182

GCD(6, 197) = ( 6 x 197 ) / 1182

= 6 / 197

= 6

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 822, 474, 197, 128 is 1
