Given numbers are 644, 725, 221, 599

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

Apply this formula for all numbers.

Step1:

LCM(644, 725) = 466900

GCD(644, 725) = ( 644 x 725 ) / 466900

= 644 / 725

= 644

Step2:

LCM(1, 221) = 221

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

= 1 / 221

= 1

Step3:

LCM(1, 599) = 599

GCD(1, 599) = ( 1 x 599 ) / 599

= 1 / 599

= 1

So, Greatest Common Divisor of 644, 725, 221, 599 is 1
