Given numbers are 247, 851, 443, 453

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

Apply this formula for all numbers.

Step1:

LCM(247, 851) = 210197

GCD(247, 851) = ( 247 x 851 ) / 210197

= 247 / 851

= 247

Step2:

LCM(1, 443) = 443

GCD(1, 443) = ( 1 x 443 ) / 443

= 1 / 443

= 1

Step3:

LCM(1, 453) = 453

GCD(1, 453) = ( 1 x 453 ) / 453

= 1 / 453

= 1

So, Greatest Common Divisor of 247, 851, 443, 453 is 1
