Given numbers are 820, 831, 440, 869
The list of prime factors of all numbers are
Prime factors of 820 are 2 x 2 x 5 x 41
Prime factors of 831 are 3 x 277
Prime factors of 440 are 2 x 2 x 2 x 5 x 11
Prime factors of 869 are 11 x 79
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 820, 831, 440, 869
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 831) = 681420
GCD(820, 831) = ( 820 x 831 ) / 681420
= 820 / 831
= 820
Step2:
LCM(1, 440) = 440
GCD(1, 440) = ( 1 x 440 ) / 440
= 1 / 440
= 1
Step3:
LCM(1, 869) = 869
GCD(1, 869) = ( 1 x 869 ) / 869
= 1 / 869
= 1
So, Greatest Common Divisor of 820, 831, 440, 869 is 1
