Given numbers are 647, 485, 406, 202

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

Apply this formula for all numbers.

Step1:

LCM(647, 485) = 313795

GCD(647, 485) = ( 647 x 485 ) / 313795

= 647 / 485

= 647

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 202) = 202

GCD(1, 202) = ( 1 x 202 ) / 202

= 1 / 202

= 1

So, Greatest Common Divisor of 647, 485, 406, 202 is 1
