Given numbers are 646, 404, 529, 248

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

Apply this formula for all numbers.

Step1:

LCM(646, 404) = 130492

GCD(646, 404) = ( 646 x 404 ) / 130492

= 646 / 404

= 646

Step2:

LCM(2, 529) = 1058

GCD(2, 529) = ( 2 x 529 ) / 1058

= 2 / 529

= 2

Step3:

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

= 1 / 248

= 1

So, Greatest Common Divisor of 646, 404, 529, 248 is 1
