The list of prime factors of all numbers are
Prime factors of 390 are 2 x 3 x 5 x 13
Prime factors of 454 are 2 x 227
Prime factors of 253 are 11 x 23
Prime factors of 731 are 17 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 390, 454, 253, 731
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 454) = 88530
GCD(390, 454) = ( 390 x 454 ) / 88530
= 390 / 454
= 390
Step2:
LCM(2, 253) = 506
GCD(2, 253) = ( 2 x 253 ) / 506
= 2 / 253
= 2
Step3:
LCM(1, 731) = 731
GCD(1, 731) = ( 1 x 731 ) / 731
= 1 / 731
= 1
So, Greatest Common Divisor of 390, 454, 253, 731 is 1
