GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 912) = 247152
GCD(813, 912) = ( 813 x 912 ) / 247152
= 813 / 912
= 813
Step2:
LCM(3, 649) = 1947
GCD(3, 649) = ( 3 x 649 ) / 1947
= 3 / 649
= 3
Step3:
LCM(1, 768) = 768
GCD(1, 768) = ( 1 x 768 ) / 768
= 1 / 768
= 1
So, Greatest Common Divisor of 813, 912, 649, 768 is 1
