Steps to Calculate GCD of 991, 717, 307, 745 using LCM Formula
Given numbers are 991, 717, 307, 745
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(991, 717) = 710547
GCD(991, 717) = ( 991 x 717 ) / 710547
= 991 / 717
= 991
Step2:
LCM(1, 307) = 307
GCD(1, 307) = ( 1 x 307 ) / 307
= 1 / 307
= 1
Step3:
LCM(1, 745) = 745
GCD(1, 745) = ( 1 x 745 ) / 745
= 1 / 745
= 1
So, Greatest Common Divisor of 991, 717, 307, 745 is 1
