Given numbers are 621, 191, 891, 907
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 191) = 118611
GCD(621, 191) = ( 621 x 191 ) / 118611
= 621 / 191
= 621
Step2:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
Step3:
LCM(1, 907) = 907
GCD(1, 907) = ( 1 x 907 ) / 907
= 1 / 907
= 1
So, Greatest Common Divisor of 621, 191, 891, 907 is 1
