Given numbers are 478, 452, 398, 186

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

Apply this formula for all numbers.

Step1:

LCM(478, 452) = 108028

GCD(478, 452) = ( 478 x 452 ) / 108028

= 478 / 452

= 478

Step2:

LCM(2, 398) = 398

GCD(2, 398) = ( 2 x 398 ) / 398

= 2 / 398

= 2

Step3:

LCM(2, 186) = 186

GCD(2, 186) = ( 2 x 186 ) / 186

= 2 / 186

= 2

So, Greatest Common Divisor of 478, 452, 398, 186 is 2
