Given numbers are 279, 690, 58, 689

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

Apply this formula for all numbers.

Step1:

LCM(279, 690) = 64170

GCD(279, 690) = ( 279 x 690 ) / 64170

= 279 / 690

= 279

Step2:

LCM(3, 58) = 174

GCD(3, 58) = ( 3 x 58 ) / 174

= 3 / 58

= 3

Step3:

LCM(1, 689) = 689

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

= 1 / 689

= 1

So, Greatest Common Divisor of 279, 690, 58, 689 is 1
