The list of prime factors of all numbers are
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 921 are 3 x 307
Prime factors of 370 are 2 x 5 x 37
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 420, 921, 370, 326
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 921) = 128940
GCD(420, 921) = ( 420 x 921 ) / 128940
= 420 / 921
= 420
Step2:
LCM(3, 370) = 1110
GCD(3, 370) = ( 3 x 370 ) / 1110
= 3 / 370
= 3
Step3:
LCM(1, 326) = 326
GCD(1, 326) = ( 1 x 326 ) / 326
= 1 / 326
= 1
So, Greatest Common Divisor of 420, 921, 370, 326 is 1
