Given numbers are 408, 316, 388, 689

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

Apply this formula for all numbers.

Step1:

LCM(408, 316) = 32232

GCD(408, 316) = ( 408 x 316 ) / 32232

= 408 / 316

= 408

Step2:

LCM(4, 388) = 388

GCD(4, 388) = ( 4 x 388 ) / 388

= 4 / 388

= 4

Step3:

LCM(4, 689) = 2756

GCD(4, 689) = ( 4 x 689 ) / 2756

= 4 / 689

= 4

So, Greatest Common Divisor of 408, 316, 388, 689 is 1
