The list of prime factors of all numbers are
Prime factors of 807 are 3 x 269
Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7
Prime factors of 505 are 5 x 101
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 807, 756, 505, 665
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(807, 756) = 203364
GCD(807, 756) = ( 807 x 756 ) / 203364
= 807 / 756
= 807
Step2:
LCM(3, 505) = 1515
GCD(3, 505) = ( 3 x 505 ) / 1515
= 3 / 505
= 3
Step3:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
So, Greatest Common Divisor of 807, 756, 505, 665 is 1
