Given numbers are 891, 788, 100, 806
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(891, 788) = 702108
GCD(891, 788) = ( 891 x 788 ) / 702108
= 891 / 788
= 891
Step2:
LCM(1, 100) = 100
GCD(1, 100) = ( 1 x 100 ) / 100
= 1 / 100
= 1
Step3:
LCM(1, 806) = 806
GCD(1, 806) = ( 1 x 806 ) / 806
= 1 / 806
= 1
So, Greatest Common Divisor of 891, 788, 100, 806 is 1
