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

Apply this formula for all numbers.

Step1:

LCM(247, 208) = 3952

GCD(247, 208) = ( 247 x 208 ) / 3952

= 247 / 208

= 247

Step2:

LCM(13, 989) = 12857

GCD(13, 989) = ( 13 x 989 ) / 12857

= 13 / 989

= 13

So, Greatest Common Divisor of 247, 208, 989 is 1
