Given numbers are 391, 207, 772, 298

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

Apply this formula for all numbers.

Step1:

LCM(391, 207) = 3519

GCD(391, 207) = ( 391 x 207 ) / 3519

= 391 / 207

= 391

Step2:

LCM(23, 772) = 17756

GCD(23, 772) = ( 23 x 772 ) / 17756

= 23 / 772

= 23

Step3:

LCM(1, 298) = 298

GCD(1, 298) = ( 1 x 298 ) / 298

= 1 / 298

= 1

So, Greatest Common Divisor of 391, 207, 772, 298 is 1
