Given numbers are 280, 203, 840, 695

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 203 are 7 x 29

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

Prime factors of 695 are 5 x 139

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

Given numbers are 280, 203, 840, 695

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

Apply this formula for all numbers.

Step1:

LCM(280, 203) = 8120

GCD(280, 203) = ( 280 x 203 ) / 8120

= 280 / 203

= 280

Step2:

LCM(7, 840) = 840

GCD(7, 840) = ( 7 x 840 ) / 840

= 7 / 840

= 7

Step3:

LCM(7, 695) = 4865

GCD(7, 695) = ( 7 x 695 ) / 4865

= 7 / 695

= 7

So, Greatest Common Divisor of 280, 203, 840, 695 is 1
