Given numbers are 644, 307, 470, 569
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 307) = 197708
GCD(644, 307) = ( 644 x 307 ) / 197708
= 644 / 307
= 644
Step2:
LCM(1, 470) = 470
GCD(1, 470) = ( 1 x 470 ) / 470
= 1 / 470
= 1
Step3:
LCM(1, 569) = 569
GCD(1, 569) = ( 1 x 569 ) / 569
= 1 / 569
= 1
So, Greatest Common Divisor of 644, 307, 470, 569 is 1
