The list of prime factors of all numbers are
Prime factors of 561 are 3 x 11 x 17
Prime factors of 700 are 2 x 2 x 5 x 5 x 7
Prime factors of 438 are 2 x 3 x 73
Prime factors of 326 are 2 x 163
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 561, 700, 438, 326
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 700) = 392700
GCD(561, 700) = ( 561 x 700 ) / 392700
= 561 / 700
= 561
Step2:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
Step3:
LCM(1, 326) = 326
GCD(1, 326) = ( 1 x 326 ) / 326
= 1 / 326
= 1
So, Greatest Common Divisor of 561, 700, 438, 326 is 1
