The list of prime factors of all numbers are
Prime factors of 679 are 7 x 97
Prime factors of 450 are 2 x 3 x 3 x 5 x 5
Prime factors of 561 are 3 x 11 x 17
Prime factors of 278 are 2 x 139
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 679, 450, 561, 278
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(679, 450) = 305550
GCD(679, 450) = ( 679 x 450 ) / 305550
= 679 / 450
= 679
Step2:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
Step3:
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
= 1 / 278
= 1
So, Greatest Common Divisor of 679, 450, 561, 278 is 1
