The list of prime factors of all numbers are
Prime factors of 690 are 2 x 3 x 5 x 23
Prime factors of 711 are 3 x 3 x 79
Prime factors of 460 are 2 x 2 x 5 x 23
Prime factors of 665 are 5 x 7 x 19
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 690, 711, 460, 665
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 711) = 163530
GCD(690, 711) = ( 690 x 711 ) / 163530
= 690 / 711
= 690
Step2:
LCM(3, 460) = 1380
GCD(3, 460) = ( 3 x 460 ) / 1380
= 3 / 460
= 3
Step3:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
So, Greatest Common Divisor of 690, 711, 460, 665 is 1
