Given numbers are 679, 420, 46, 390

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

Apply this formula for all numbers.

Step1:

LCM(679, 420) = 40740

GCD(679, 420) = ( 679 x 420 ) / 40740

= 679 / 420

= 679

Step2:

LCM(7, 46) = 322

GCD(7, 46) = ( 7 x 46 ) / 322

= 7 / 46

= 7

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 679, 420, 46, 390 is 1
