Given numbers are 620, 230, 405, 604
The list of prime factors of all numbers are
Prime factors of 620 are 2 x 2 x 5 x 31
Prime factors of 230 are 2 x 5 x 23
Prime factors of 405 are 3 x 3 x 3 x 3 x 5
Prime factors of 604 are 2 x 2 x 151
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 620, 230, 405, 604
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 230) = 14260
GCD(620, 230) = ( 620 x 230 ) / 14260
= 620 / 230
= 620
Step2:
LCM(10, 405) = 810
GCD(10, 405) = ( 10 x 405 ) / 810
= 10 / 405
= 10
Step3:
LCM(5, 604) = 3020
GCD(5, 604) = ( 5 x 604 ) / 3020
= 5 / 604
= 5
So, Greatest Common Divisor of 620, 230, 405, 604 is 1
