Given numbers are 304, 639, 686, 437

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

Apply this formula for all numbers.

Step1:

LCM(304, 639) = 194256

GCD(304, 639) = ( 304 x 639 ) / 194256

= 304 / 639

= 304

Step2:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

Step3:

LCM(1, 437) = 437

GCD(1, 437) = ( 1 x 437 ) / 437

= 1 / 437

= 1

So, Greatest Common Divisor of 304, 639, 686, 437 is 1
