Given numbers are 395, 980, 307, 493
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(395, 980) = 77420
GCD(395, 980) = ( 395 x 980 ) / 77420
= 395 / 980
= 395
Step2:
LCM(5, 307) = 1535
GCD(5, 307) = ( 5 x 307 ) / 1535
= 5 / 307
= 5
Step3:
LCM(1, 493) = 493
GCD(1, 493) = ( 1 x 493 ) / 493
= 1 / 493
= 1
So, Greatest Common Divisor of 395, 980, 307, 493 is 1
