Given numbers are 247, 559, 847, 400

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

Apply this formula for all numbers.

Step1:

LCM(247, 559) = 10621

GCD(247, 559) = ( 247 x 559 ) / 10621

= 247 / 559

= 247

Step2:

LCM(13, 847) = 11011

GCD(13, 847) = ( 13 x 847 ) / 11011

= 13 / 847

= 13

Step3:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

So, Greatest Common Divisor of 247, 559, 847, 400 is 1
