Given numbers are 199, 643, 978, 699

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

Apply this formula for all numbers.

Step1:

LCM(199, 643) = 127957

GCD(199, 643) = ( 199 x 643 ) / 127957

= 199 / 643

= 199

Step2:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

Step3:

LCM(1, 699) = 699

GCD(1, 699) = ( 1 x 699 ) / 699

= 1 / 699

= 1

So, Greatest Common Divisor of 199, 643, 978, 699 is 1
