Given numbers are 815, 812, 814, 820
The list of prime factors of all numbers are
Prime factors of 815 are 5 x 163
Prime factors of 812 are 2 x 2 x 7 x 29
Prime factors of 814 are 2 x 11 x 37
Prime factors of 820 are 2 x 2 x 5 x 41
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 815, 812, 814, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 812) = 661780
GCD(815, 812) = ( 815 x 812 ) / 661780
= 815 / 812
= 815
Step2:
LCM(1, 814) = 814
GCD(1, 814) = ( 1 x 814 ) / 814
= 1 / 814
= 1
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 815, 812, 814, 820 is 1
