Given numbers are 297, 175, 197, 639

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

Apply this formula for all numbers.

Step1:

LCM(297, 175) = 51975

GCD(297, 175) = ( 297 x 175 ) / 51975

= 297 / 175

= 297

Step2:

LCM(1, 197) = 197

GCD(1, 197) = ( 1 x 197 ) / 197

= 1 / 197

= 1

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 297, 175, 197, 639 is 1
