Given numbers are 245, 590, 258, 857

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

Apply this formula for all numbers.

Step1:

LCM(245, 590) = 28910

GCD(245, 590) = ( 245 x 590 ) / 28910

= 245 / 590

= 245

Step2:

LCM(5, 258) = 1290

GCD(5, 258) = ( 5 x 258 ) / 1290

= 5 / 258

= 5

Step3:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

So, Greatest Common Divisor of 245, 590, 258, 857 is 1
