Given numbers are 840, 235, 991, 823
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 235) = 39480
GCD(840, 235) = ( 840 x 235 ) / 39480
= 840 / 235
= 840
Step2:
LCM(5, 991) = 4955
GCD(5, 991) = ( 5 x 991 ) / 4955
= 5 / 991
= 5
Step3:
LCM(1, 823) = 823
GCD(1, 823) = ( 1 x 823 ) / 823
= 1 / 823
= 1
So, Greatest Common Divisor of 840, 235, 991, 823 is 1
