Given numbers are 380, 668, 428, 263

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

Apply this formula for all numbers.

Step1:

LCM(380, 668) = 63460

GCD(380, 668) = ( 380 x 668 ) / 63460

= 380 / 668

= 380

Step2:

LCM(4, 428) = 428

GCD(4, 428) = ( 4 x 428 ) / 428

= 4 / 428

= 4

Step3:

LCM(4, 263) = 1052

GCD(4, 263) = ( 4 x 263 ) / 1052

= 4 / 263

= 4

So, Greatest Common Divisor of 380, 668, 428, 263 is 1
