Given numbers are 279, 920, 64, 685

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

Apply this formula for all numbers.

Step1:

LCM(279, 920) = 256680

GCD(279, 920) = ( 279 x 920 ) / 256680

= 279 / 920

= 279

Step2:

LCM(1, 64) = 64

GCD(1, 64) = ( 1 x 64 ) / 64

= 1 / 64

= 1

Step3:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

So, Greatest Common Divisor of 279, 920, 64, 685 is 1
