Given numbers are 891, 115, 907, 843
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(891, 115) = 102465
GCD(891, 115) = ( 891 x 115 ) / 102465
= 891 / 115
= 891
Step2:
LCM(1, 907) = 907
GCD(1, 907) = ( 1 x 907 ) / 907
= 1 / 907
= 1
Step3:
LCM(1, 843) = 843
GCD(1, 843) = ( 1 x 843 ) / 843
= 1 / 843
= 1
So, Greatest Common Divisor of 891, 115, 907, 843 is 1
