Given numbers are 475, 642, 217, 133

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

Apply this formula for all numbers.

Step1:

LCM(475, 642) = 304950

GCD(475, 642) = ( 475 x 642 ) / 304950

= 475 / 642

= 475

Step2:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

Step3:

LCM(1, 133) = 133

GCD(1, 133) = ( 1 x 133 ) / 133

= 1 / 133

= 1

So, Greatest Common Divisor of 475, 642, 217, 133 is 1
