Given numbers are 247, 694, 840, 160

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 694 are 2 x 347

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

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 247, 694, 840, 160

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

Apply this formula for all numbers.

Step1:

LCM(247, 694) = 171418

GCD(247, 694) = ( 247 x 694 ) / 171418

= 247 / 694

= 247

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 160) = 160

GCD(1, 160) = ( 1 x 160 ) / 160

= 1 / 160

= 1

So, Greatest Common Divisor of 247, 694, 840, 160 is 1
