Given numbers are 221, 325, 443, 647

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

Apply this formula for all numbers.

Step1:

LCM(221, 325) = 5525

GCD(221, 325) = ( 221 x 325 ) / 5525

= 221 / 325

= 221

Step2:

LCM(13, 443) = 5759

GCD(13, 443) = ( 13 x 443 ) / 5759

= 13 / 443

= 13

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 221, 325, 443, 647 is 1
