Given numbers are 198, 644, 84, 554

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

Apply this formula for all numbers.

Step1:

LCM(198, 644) = 63756

GCD(198, 644) = ( 198 x 644 ) / 63756

= 198 / 644

= 198

Step2:

LCM(2, 84) = 84

GCD(2, 84) = ( 2 x 84 ) / 84

= 2 / 84

= 2

Step3:

LCM(2, 554) = 554

GCD(2, 554) = ( 2 x 554 ) / 554

= 2 / 554

= 2

So, Greatest Common Divisor of 198, 644, 84, 554 is 2
