Given numbers are 428, 979, 689, 799

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

Apply this formula for all numbers.

Step1:

LCM(428, 979) = 419012

GCD(428, 979) = ( 428 x 979 ) / 419012

= 428 / 979

= 428

Step2:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

Step3:

LCM(1, 799) = 799

GCD(1, 799) = ( 1 x 799 ) / 799

= 1 / 799

= 1

So, Greatest Common Divisor of 428, 979, 689, 799 is 1
