Given numbers are 644, 225, 592, 305
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 225) = 144900
GCD(644, 225) = ( 644 x 225 ) / 144900
= 644 / 225
= 644
Step2:
LCM(1, 592) = 592
GCD(1, 592) = ( 1 x 592 ) / 592
= 1 / 592
= 1
Step3:
LCM(1, 305) = 305
GCD(1, 305) = ( 1 x 305 ) / 305
= 1 / 305
= 1
So, Greatest Common Divisor of 644, 225, 592, 305 is 1
