Given numbers are 689, 504, 355, 694
The list of prime factors of all numbers are
Prime factors of 689 are 13 x 53
Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7
Prime factors of 355 are 5 x 71
Prime factors of 694 are 2 x 347
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 689, 504, 355, 694
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 504) = 347256
GCD(689, 504) = ( 689 x 504 ) / 347256
= 689 / 504
= 689
Step2:
LCM(1, 355) = 355
GCD(1, 355) = ( 1 x 355 ) / 355
= 1 / 355
= 1
Step3:
LCM(1, 694) = 694
GCD(1, 694) = ( 1 x 694 ) / 694
= 1 / 694
= 1
So, Greatest Common Divisor of 689, 504, 355, 694 is 1
