Given numbers are 971, 320, 65, 889

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

Apply this formula for all numbers.

Step1:

LCM(971, 320) = 310720

GCD(971, 320) = ( 971 x 320 ) / 310720

= 971 / 320

= 971

Step2:

LCM(1, 65) = 65

GCD(1, 65) = ( 1 x 65 ) / 65

= 1 / 65

= 1

Step3:

LCM(1, 889) = 889

GCD(1, 889) = ( 1 x 889 ) / 889

= 1 / 889

= 1

So, Greatest Common Divisor of 971, 320, 65, 889 is 1
