Given numbers are 221, 554, 598, 644

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

Apply this formula for all numbers.

Step1:

LCM(221, 554) = 122434

GCD(221, 554) = ( 221 x 554 ) / 122434

= 221 / 554

= 221

Step2:

LCM(1, 598) = 598

GCD(1, 598) = ( 1 x 598 ) / 598

= 1 / 598

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 221, 554, 598, 644 is 1
