Given numbers are 971, 644, 397, 851

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

Apply this formula for all numbers.

Step1:

LCM(971, 644) = 625324

GCD(971, 644) = ( 971 x 644 ) / 625324

= 971 / 644

= 971

Step2:

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

= 1 / 397

= 1

Step3:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

So, Greatest Common Divisor of 971, 644, 397, 851 is 1
