Given numbers are 821, 831, 155, 954

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 831 are 3 x 277

Prime factors of 155 are 5 x 31

Prime factors of 954 are 2 x 3 x 3 x 53

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 821, 831, 155, 954

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(821, 831) = 682251

GCD(821, 831) = ( 821 x 831 ) / 682251

= 821 / 831

= 821

Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

Step3:

LCM(1, 954) = 954

GCD(1, 954) = ( 1 x 954 ) / 954

= 1 / 954

= 1

So, Greatest Common Divisor of 821, 831, 155, 954 is 1
