Given numbers are 221, 357, 64, 171

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

Apply this formula for all numbers.

Step1:

LCM(221, 357) = 4641

GCD(221, 357) = ( 221 x 357 ) / 4641

= 221 / 357

= 221

Step2:

LCM(17, 64) = 1088

GCD(17, 64) = ( 17 x 64 ) / 1088

= 17 / 64

= 17

Step3:

LCM(1, 171) = 171

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

= 1 / 171

= 1

So, Greatest Common Divisor of 221, 357, 64, 171 is 1
