GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(991, 109) = 108019
GCD(991, 109) = ( 991 x 109 ) / 108019
= 991 / 109
= 991
Step2:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
Step3:
LCM(1, 833) = 833
GCD(1, 833) = ( 1 x 833 ) / 833
= 1 / 833
= 1
So, Greatest Common Divisor of 991, 109, 438, 833 is 1
