Given numbers are 245, 790, 242, 854

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

Apply this formula for all numbers.

Step1:

LCM(245, 790) = 38710

GCD(245, 790) = ( 245 x 790 ) / 38710

= 245 / 790

= 245

Step2:

LCM(5, 242) = 1210

GCD(5, 242) = ( 5 x 242 ) / 1210

= 5 / 242

= 5

Step3:

LCM(1, 854) = 854

GCD(1, 854) = ( 1 x 854 ) / 854

= 1 / 854

= 1

So, Greatest Common Divisor of 245, 790, 242, 854 is 1
