The list of prime factors of all numbers are
Prime factors of 831 are 3 x 277
Prime factors of 505 are 5 x 101
Prime factors of 750 are 2 x 3 x 5 x 5 x 5
Prime factors of 220 are 2 x 2 x 5 x 11
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 831, 505, 750, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(831, 505) = 419655
GCD(831, 505) = ( 831 x 505 ) / 419655
= 831 / 505
= 831
Step2:
LCM(1, 750) = 750
GCD(1, 750) = ( 1 x 750 ) / 750
= 1 / 750
= 1
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 831, 505, 750, 220 is 1
