Given numbers are 900, 279, 915, 161
The list of prime factors of all numbers are
Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5
Prime factors of 279 are 3 x 3 x 31
Prime factors of 915 are 3 x 5 x 61
Prime factors of 161 are 7 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 900, 279, 915, 161
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(900, 279) = 27900
GCD(900, 279) = ( 900 x 279 ) / 27900
= 900 / 279
= 900
Step2:
LCM(9, 915) = 2745
GCD(9, 915) = ( 9 x 915 ) / 2745
= 9 / 915
= 9
Step3:
LCM(3, 161) = 483
GCD(3, 161) = ( 3 x 161 ) / 483
= 3 / 161
= 3
So, Greatest Common Divisor of 900, 279, 915, 161 is 1
