Given numbers are 425, 145, 818, 388

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

Apply this formula for all numbers.

Step1:

LCM(425, 145) = 12325

GCD(425, 145) = ( 425 x 145 ) / 12325

= 425 / 145

= 425

Step2:

LCM(5, 818) = 4090

GCD(5, 818) = ( 5 x 818 ) / 4090

= 5 / 818

= 5

Step3:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

So, Greatest Common Divisor of 425, 145, 818, 388 is 1
