Given numbers are 324, 451, 620, 821
The list of prime factors of all numbers are
Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3
Prime factors of 451 are 11 x 41
Prime factors of 620 are 2 x 2 x 5 x 31
Prime factors of 821 are 821
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 324, 451, 620, 821
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(324, 451) = 146124
GCD(324, 451) = ( 324 x 451 ) / 146124
= 324 / 451
= 324
Step2:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
Step3:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
So, Greatest Common Divisor of 324, 451, 620, 821 is 1
