Given numbers are 247, 817, 235, 913

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

Apply this formula for all numbers.

Step1:

LCM(247, 817) = 10621

GCD(247, 817) = ( 247 x 817 ) / 10621

= 247 / 817

= 247

Step2:

LCM(19, 235) = 4465

GCD(19, 235) = ( 19 x 235 ) / 4465

= 19 / 235

= 19

Step3:

LCM(1, 913) = 913

GCD(1, 913) = ( 1 x 913 ) / 913

= 1 / 913

= 1

So, Greatest Common Divisor of 247, 817, 235, 913 is 1
