Given numbers are 921, 623, 220, 547

The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 623 are 7 x 89

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 547 are 547

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

Given numbers are 921, 623, 220, 547

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

Apply this formula for all numbers.

Step1:

LCM(921, 623) = 573783

GCD(921, 623) = ( 921 x 623 ) / 573783

= 921 / 623

= 921

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 547) = 547

GCD(1, 547) = ( 1 x 547 ) / 547

= 1 / 547

= 1

So, Greatest Common Divisor of 921, 623, 220, 547 is 1
