Given numbers are 820, 900, 612, 813
The list of prime factors of all numbers are
Prime factors of 820 are 2 x 2 x 5 x 41
Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5
Prime factors of 612 are 2 x 2 x 3 x 3 x 17
Prime factors of 813 are 3 x 271
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 820, 900, 612, 813
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 900) = 36900
GCD(820, 900) = ( 820 x 900 ) / 36900
= 820 / 900
= 820
Step2:
LCM(20, 612) = 3060
GCD(20, 612) = ( 20 x 612 ) / 3060
= 20 / 612
= 20
Step3:
LCM(4, 813) = 3252
GCD(4, 813) = ( 4 x 813 ) / 3252
= 4 / 813
= 4
So, Greatest Common Divisor of 820, 900, 612, 813 is 1
