Given numbers are 847, 977, 851, 249

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

Apply this formula for all numbers.

Step1:

LCM(847, 977) = 827519

GCD(847, 977) = ( 847 x 977 ) / 827519

= 847 / 977

= 847

Step2:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

Step3:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

So, Greatest Common Divisor of 847, 977, 851, 249 is 1
