GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(891, 408) = 121176
GCD(891, 408) = ( 891 x 408 ) / 121176
= 891 / 408
= 891
Step2:
LCM(3, 765) = 765
GCD(3, 765) = ( 3 x 765 ) / 765
= 3 / 765
= 3
Step3:
LCM(3, 935) = 2805
GCD(3, 935) = ( 3 x 935 ) / 2805
= 3 / 935
= 3
So, Greatest Common Divisor of 891, 408, 765, 935 is 1
