Prime factors of 455 are 5 x 7 x 13
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 793, 270, 455, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(793, 270) = 214110
GCD(793, 270) = ( 793 x 270 ) / 214110
= 793 / 270
= 793
Step2:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 793, 270, 455, 621 is 1
