Given numbers are 380, 428, 388, 245

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

Apply this formula for all numbers.

Step1:

LCM(380, 428) = 40660

GCD(380, 428) = ( 380 x 428 ) / 40660

= 380 / 428

= 380

Step2:

LCM(4, 388) = 388

GCD(4, 388) = ( 4 x 388 ) / 388

= 4 / 388

= 4

Step3:

LCM(4, 245) = 980

GCD(4, 245) = ( 4 x 245 ) / 980

= 4 / 245

= 4

So, Greatest Common Divisor of 380, 428, 388, 245 is 1
