Given numbers are 245, 427, 578, 743

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

Apply this formula for all numbers.

Step1:

LCM(245, 427) = 14945

GCD(245, 427) = ( 245 x 427 ) / 14945

= 245 / 427

= 245

Step2:

LCM(7, 578) = 4046

GCD(7, 578) = ( 7 x 578 ) / 4046

= 7 / 578

= 7

Step3:

LCM(1, 743) = 743

GCD(1, 743) = ( 1 x 743 ) / 743

= 1 / 743

= 1

So, Greatest Common Divisor of 245, 427, 578, 743 is 1
