Given numbers are 728, 805, 991, 313
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(728, 805) = 83720
GCD(728, 805) = ( 728 x 805 ) / 83720
= 728 / 805
= 728
Step2:
LCM(7, 991) = 6937
GCD(7, 991) = ( 7 x 991 ) / 6937
= 7 / 991
= 7
Step3:
LCM(1, 313) = 313
GCD(1, 313) = ( 1 x 313 ) / 313
= 1 / 313
= 1
So, Greatest Common Divisor of 728, 805, 991, 313 is 1
