Given numbers are 648, 393, 274, 257

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

Apply this formula for all numbers.

Step1:

LCM(648, 393) = 84888

GCD(648, 393) = ( 648 x 393 ) / 84888

= 648 / 393

= 648

Step2:

LCM(3, 274) = 822

GCD(3, 274) = ( 3 x 274 ) / 822

= 3 / 274

= 3

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 648, 393, 274, 257 is 1
