Given numbers are 801, 703, 648, 455

The list of prime factors of all numbers are

Prime factors of 801 are 3 x 3 x 89

Prime factors of 703 are 19 x 37

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 801, 703, 648, 455

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

Apply this formula for all numbers.

Step1:

LCM(801, 703) = 563103

GCD(801, 703) = ( 801 x 703 ) / 563103

= 801 / 703

= 801

Step2:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 801, 703, 648, 455 is 1
