Given numbers are 821, 972, 942, 803

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 942 are 2 x 3 x 157

Prime factors of 803 are 11 x 73

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

Given numbers are 821, 972, 942, 803

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

Apply this formula for all numbers.

Step1:

LCM(821, 972) = 798012

GCD(821, 972) = ( 821 x 972 ) / 798012

= 821 / 972

= 821

Step2:

LCM(1, 942) = 942

GCD(1, 942) = ( 1 x 942 ) / 942

= 1 / 942

= 1

Step3:

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

= 1 / 803

= 1

So, Greatest Common Divisor of 821, 972, 942, 803 is 1
