Given numbers are 527, 861, 408, 221

The list of prime factors of all numbers are

Prime factors of 527 are 17 x 31

Prime factors of 861 are 3 x 7 x 41

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 221 are 13 x 17

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 527, 861, 408, 221

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

Apply this formula for all numbers.

Step1:

LCM(527, 861) = 453747

GCD(527, 861) = ( 527 x 861 ) / 453747

= 527 / 861

= 527

Step2:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 527, 861, 408, 221 is 1
