Given numbers are 457, 563, 130, 842

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

Apply this formula for all numbers.

Step1:

LCM(457, 563) = 257291

GCD(457, 563) = ( 457 x 563 ) / 257291

= 457 / 563

= 457

Step2:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 457, 563, 130, 842 is 1
