Given numbers are 307, 638, 867, 153

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

Apply this formula for all numbers.

Step1:

LCM(307, 638) = 195866

GCD(307, 638) = ( 307 x 638 ) / 195866

= 307 / 638

= 307

Step2:

LCM(1, 867) = 867

GCD(1, 867) = ( 1 x 867 ) / 867

= 1 / 867

= 1

Step3:

LCM(1, 153) = 153

GCD(1, 153) = ( 1 x 153 ) / 153

= 1 / 153

= 1

So, Greatest Common Divisor of 307, 638, 867, 153 is 1
