Given numbers are 252, 196, 864, 685

The list of prime factors of all numbers are

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 196 are 2 x 2 x 7 x 7

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 685 are 5 x 137

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

Given numbers are 252, 196, 864, 685

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

Apply this formula for all numbers.

Step1:

LCM(252, 196) = 1764

GCD(252, 196) = ( 252 x 196 ) / 1764

= 252 / 196

= 252

Step2:

LCM(28, 864) = 6048

GCD(28, 864) = ( 28 x 864 ) / 6048

= 28 / 864

= 28

Step3:

LCM(4, 685) = 2740

GCD(4, 685) = ( 4 x 685 ) / 2740

= 4 / 685

= 4

So, Greatest Common Divisor of 252, 196, 864, 685 is 1
