Given numbers are 865, 921, 785, 994
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(865, 921) = 796665
GCD(865, 921) = ( 865 x 921 ) / 796665
= 865 / 921
= 865
Step2:
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
= 1 / 785
= 1
Step3:
LCM(1, 994) = 994
GCD(1, 994) = ( 1 x 994 ) / 994
= 1 / 994
= 1
So, Greatest Common Divisor of 865, 921, 785, 994 is 1
