Given numbers are 971, 685, 163, 640

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

Apply this formula for all numbers.

Step1:

LCM(971, 685) = 665135

GCD(971, 685) = ( 971 x 685 ) / 665135

= 971 / 685

= 971

Step2:

LCM(1, 163) = 163

GCD(1, 163) = ( 1 x 163 ) / 163

= 1 / 163

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 971, 685, 163, 640 is 1
