Given numbers are 307, 820, 184, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(307, 820) = 251740
GCD(307, 820) = ( 307 x 820 ) / 251740
= 307 / 820
= 307
Step2:
LCM(1, 184) = 184
GCD(1, 184) = ( 1 x 184 ) / 184
= 1 / 184
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 307, 820, 184, 644 is 1
