Given numbers are 856, 803, 788, 905
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(856, 803) = 687368
GCD(856, 803) = ( 856 x 803 ) / 687368
= 856 / 803
= 856
Step2:
LCM(1, 788) = 788
GCD(1, 788) = ( 1 x 788 ) / 788
= 1 / 788
= 1
Step3:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
So, Greatest Common Divisor of 856, 803, 788, 905 is 1
