Given numbers are 280, 481, 244, 621
The list of prime factors of all numbers are
Prime factors of 280 are 2 x 2 x 2 x 5 x 7
Prime factors of 481 are 13 x 37
Prime factors of 244 are 2 x 2 x 61
Prime factors of 621 are 3 x 3 x 3 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 280, 481, 244, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 481) = 134680
GCD(280, 481) = ( 280 x 481 ) / 134680
= 280 / 481
= 280
Step2:
LCM(1, 244) = 244
GCD(1, 244) = ( 1 x 244 ) / 244
= 1 / 244
= 1
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 280, 481, 244, 621 is 1
