Given numbers are 248, 491, 668, 558

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

Apply this formula for all numbers.

Step1:

LCM(248, 491) = 121768

GCD(248, 491) = ( 248 x 491 ) / 121768

= 248 / 491

= 248

Step2:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

Step3:

LCM(1, 558) = 558

GCD(1, 558) = ( 1 x 558 ) / 558

= 1 / 558

= 1

So, Greatest Common Divisor of 248, 491, 668, 558 is 1
