Given numbers are 401, 253, 354, 455
The list of prime factors of all numbers are
Prime factors of 401 are 401
Prime factors of 253 are 11 x 23
Prime factors of 354 are 2 x 3 x 59
Prime factors of 455 are 5 x 7 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 401, 253, 354, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 253) = 101453
GCD(401, 253) = ( 401 x 253 ) / 101453
= 401 / 253
= 401
Step2:
LCM(1, 354) = 354
GCD(1, 354) = ( 1 x 354 ) / 354
= 1 / 354
= 1
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 401, 253, 354, 455 is 1
