Given numbers are 245, 858, 551, 311

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

Apply this formula for all numbers.

Step1:

LCM(245, 858) = 210210

GCD(245, 858) = ( 245 x 858 ) / 210210

= 245 / 858

= 245

Step2:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

Step3:

LCM(1, 311) = 311

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

= 1 / 311

= 1

So, Greatest Common Divisor of 245, 858, 551, 311 is 1
