Given numbers are 905, 921, 913, 890

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

Apply this formula for all numbers.

Step1:

LCM(905, 921) = 833505

GCD(905, 921) = ( 905 x 921 ) / 833505

= 905 / 921

= 905

Step2:

LCM(1, 913) = 913

GCD(1, 913) = ( 1 x 913 ) / 913

= 1 / 913

= 1

Step3:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

So, Greatest Common Divisor of 905, 921, 913, 890 is 1
