Given numbers are 811, 504, 993, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(811, 504) = 408744
GCD(811, 504) = ( 811 x 504 ) / 408744
= 811 / 504
= 811
Step2:
LCM(1, 993) = 993
GCD(1, 993) = ( 1 x 993 ) / 993
= 1 / 993
= 1
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 811, 504, 993, 643 is 1
