Given numbers are 247, 686, 853, 612

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

Apply this formula for all numbers.

Step1:

LCM(247, 686) = 169442

GCD(247, 686) = ( 247 x 686 ) / 169442

= 247 / 686

= 247

Step2:

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

= 1 / 853

= 1

Step3:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

So, Greatest Common Divisor of 247, 686, 853, 612 is 1
