Given numbers are 731, 681, 211, 915
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(731, 681) = 497811
GCD(731, 681) = ( 731 x 681 ) / 497811
= 731 / 681
= 731
Step2:
LCM(1, 211) = 211
GCD(1, 211) = ( 1 x 211 ) / 211
= 1 / 211
= 1
Step3:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
So, Greatest Common Divisor of 731, 681, 211, 915 is 1
