Given numbers are 400, 161, 420, 483
The list of prime factors of all numbers are
Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5
Prime factors of 161 are 7 x 23
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 483 are 3 x 7 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 400, 161, 420, 483
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 161) = 64400
GCD(400, 161) = ( 400 x 161 ) / 64400
= 400 / 161
= 400
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 483) = 483
GCD(1, 483) = ( 1 x 483 ) / 483
= 1 / 483
= 1
So, Greatest Common Divisor of 400, 161, 420, 483 is 1
