Given numbers are 647, 495, 237, 171

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

Apply this formula for all numbers.

Step1:

LCM(647, 495) = 320265

GCD(647, 495) = ( 647 x 495 ) / 320265

= 647 / 495

= 647

Step2:

LCM(1, 237) = 237

GCD(1, 237) = ( 1 x 237 ) / 237

= 1 / 237

= 1

Step3:

LCM(1, 171) = 171

GCD(1, 171) = ( 1 x 171 ) / 171

= 1 / 171

= 1

So, Greatest Common Divisor of 647, 495, 237, 171 is 1
