The list of prime factors of all numbers are
Prime factors of 805 are 5 x 7 x 23
Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5
Prime factors of 258 are 2 x 3 x 43
Prime factors of 398 are 2 x 199
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 805, 900, 258, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(805, 900) = 144900
GCD(805, 900) = ( 805 x 900 ) / 144900
= 805 / 900
= 805
Step2:
LCM(5, 258) = 1290
GCD(5, 258) = ( 5 x 258 ) / 1290
= 5 / 258
= 5
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 805, 900, 258, 398 is 1
