Given numbers are 400, 421, 403, 381
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 421 are 421
Prime factors of 403 are 13 x 31
Prime factors of 381 are 3 x 127
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 400, 421, 403, 381
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 421) = 168400
GCD(400, 421) = ( 400 x 421 ) / 168400
= 400 / 421
= 400
Step2:
LCM(1, 403) = 403
GCD(1, 403) = ( 1 x 403 ) / 403
= 1 / 403
= 1
Step3:
LCM(1, 381) = 381
GCD(1, 381) = ( 1 x 381 ) / 381
= 1 / 381
= 1
So, Greatest Common Divisor of 400, 421, 403, 381 is 1
