The list of prime factors of all numbers are
Prime factors of 980 are 2 x 2 x 5 x 7 x 7
Prime factors of 253 are 11 x 23
Prime factors of 393 are 3 x 131
Prime factors of 457 are 457
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 980, 253, 393, 457
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 253) = 247940
GCD(980, 253) = ( 980 x 253 ) / 247940
= 980 / 253
= 980
Step2:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
Step3:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
So, Greatest Common Divisor of 980, 253, 393, 457 is 1
