Given numbers are 990, 332, 991, 858
The list of prime factors of all numbers are
Prime factors of 990 are 2 x 3 x 3 x 5 x 11
Prime factors of 332 are 2 x 2 x 83
Prime factors of 991 are 991
Prime factors of 858 are 2 x 3 x 11 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 990, 332, 991, 858
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 332) = 164340
GCD(990, 332) = ( 990 x 332 ) / 164340
= 990 / 332
= 990
Step2:
LCM(2, 991) = 1982
GCD(2, 991) = ( 2 x 991 ) / 1982
= 2 / 991
= 2
Step3:
LCM(1, 858) = 858
GCD(1, 858) = ( 1 x 858 ) / 858
= 1 / 858
= 1
So, Greatest Common Divisor of 990, 332, 991, 858 is 1
