Given numbers are 801, 840, 174, 647

The list of prime factors of all numbers are

Prime factors of 801 are 3 x 3 x 89

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 174 are 2 x 3 x 29

Prime factors of 647 are 647

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

Given numbers are 801, 840, 174, 647

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

Apply this formula for all numbers.

Step1:

LCM(801, 840) = 224280

GCD(801, 840) = ( 801 x 840 ) / 224280

= 801 / 840

= 801

Step2:

LCM(3, 174) = 174

GCD(3, 174) = ( 3 x 174 ) / 174

= 3 / 174

= 3

Step3:

LCM(3, 647) = 1941

GCD(3, 647) = ( 3 x 647 ) / 1941

= 3 / 647

= 3

So, Greatest Common Divisor of 801, 840, 174, 647 is 1
