Given numbers are 245, 168, 758, 253

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

Apply this formula for all numbers.

Step1:

LCM(245, 168) = 5880

GCD(245, 168) = ( 245 x 168 ) / 5880

= 245 / 168

= 245

Step2:

LCM(7, 758) = 5306

GCD(7, 758) = ( 7 x 758 ) / 5306

= 7 / 758

= 7

Step3:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1

So, Greatest Common Divisor of 245, 168, 758, 253 is 1
