Given numbers are 813, 417, 168, 356
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 417) = 113007
GCD(813, 417) = ( 813 x 417 ) / 113007
= 813 / 417
= 813
Step2:
LCM(3, 168) = 168
GCD(3, 168) = ( 3 x 168 ) / 168
= 3 / 168
= 3
Step3:
LCM(3, 356) = 1068
GCD(3, 356) = ( 3 x 356 ) / 1068
= 3 / 356
= 3
So, Greatest Common Divisor of 813, 417, 168, 356 is 1
