Given numbers are 398, 121, 253, 671

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

Apply this formula for all numbers.

Step1:

LCM(398, 121) = 48158

GCD(398, 121) = ( 398 x 121 ) / 48158

= 398 / 121

= 398

Step2:

LCM(1, 253) = 253

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

= 1 / 253

= 1

Step3:

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

= 1 / 671

= 1

So, Greatest Common Divisor of 398, 121, 253, 671 is 1
