Given numbers are 315, 143, 261, 163

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

Apply this formula for all numbers.

Step1:

LCM(315, 143) = 45045

GCD(315, 143) = ( 315 x 143 ) / 45045

= 315 / 143

= 315

Step2:

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

= 1 / 261

= 1

Step3:

LCM(1, 163) = 163

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

= 1 / 163

= 1

So, Greatest Common Divisor of 315, 143, 261, 163 is 1
