Given numbers are 849, 865, 996, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(849, 865) = 734385
GCD(849, 865) = ( 849 x 865 ) / 734385
= 849 / 865
= 849
Step2:
LCM(1, 996) = 996
GCD(1, 996) = ( 1 x 996 ) / 996
= 1 / 996
= 1
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 849, 865, 996, 820 is 1
