Given numbers are 297, 263, 690, 491

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

Apply this formula for all numbers.

Step1:

LCM(297, 263) = 78111

GCD(297, 263) = ( 297 x 263 ) / 78111

= 297 / 263

= 297

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

So, Greatest Common Divisor of 297, 263, 690, 491 is 1
