Given numbers are 391, 648, 117, 311

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

Apply this formula for all numbers.

Step1:

LCM(391, 648) = 253368

GCD(391, 648) = ( 391 x 648 ) / 253368

= 391 / 648

= 391

Step2:

LCM(1, 117) = 117

GCD(1, 117) = ( 1 x 117 ) / 117

= 1 / 117

= 1

Step3:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

So, Greatest Common Divisor of 391, 648, 117, 311 is 1
