Given numbers are 647, 676, 799, 578

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

Apply this formula for all numbers.

Step1:

LCM(647, 676) = 437372

GCD(647, 676) = ( 647 x 676 ) / 437372

= 647 / 676

= 647

Step2:

LCM(1, 799) = 799

GCD(1, 799) = ( 1 x 799 ) / 799

= 1 / 799

= 1

Step3:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

So, Greatest Common Divisor of 647, 676, 799, 578 is 1
