Given numbers are 905, 385, 971, 394

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

Apply this formula for all numbers.

Step1:

LCM(905, 385) = 69685

GCD(905, 385) = ( 905 x 385 ) / 69685

= 905 / 385

= 905

Step2:

LCM(5, 971) = 4855

GCD(5, 971) = ( 5 x 971 ) / 4855

= 5 / 971

= 5

Step3:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

So, Greatest Common Divisor of 905, 385, 971, 394 is 1
