Given numbers are 154, 420, 695, 816

The list of prime factors of all numbers are

Prime factors of 154 are 2 x 7 x 11

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 695 are 5 x 139

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

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

Given numbers are 154, 420, 695, 816

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

Apply this formula for all numbers.

Step1:

LCM(154, 420) = 4620

GCD(154, 420) = ( 154 x 420 ) / 4620

= 154 / 420

= 154

Step2:

LCM(14, 695) = 9730

GCD(14, 695) = ( 14 x 695 ) / 9730

= 14 / 695

= 14

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 154, 420, 695, 816 is 1
