Given numbers are 803, 804, 945, 644

The list of prime factors of all numbers are

Prime factors of 803 are 11 x 73

Prime factors of 804 are 2 x 2 x 3 x 67

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 803, 804, 945, 644

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

Apply this formula for all numbers.

Step1:

LCM(803, 804) = 645612

GCD(803, 804) = ( 803 x 804 ) / 645612

= 803 / 804

= 803

Step2:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 803, 804, 945, 644 is 1
