Given numbers are 640, 412, 931, 163

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

Apply this formula for all numbers.

Step1:

LCM(640, 412) = 65920

GCD(640, 412) = ( 640 x 412 ) / 65920

= 640 / 412

= 640

Step2:

LCM(4, 931) = 3724

GCD(4, 931) = ( 4 x 931 ) / 3724

= 4 / 931

= 4

Step3:

LCM(1, 163) = 163

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

= 1 / 163

= 1

So, Greatest Common Divisor of 640, 412, 931, 163 is 1
