Given numbers are 628, 178, 671, 863

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

Apply this formula for all numbers.

Step1:

LCM(628, 178) = 55892

GCD(628, 178) = ( 628 x 178 ) / 55892

= 628 / 178

= 628

Step2:

LCM(2, 671) = 1342

GCD(2, 671) = ( 2 x 671 ) / 1342

= 2 / 671

= 2

Step3:

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

= 1 / 863

= 1

So, Greatest Common Divisor of 628, 178, 671, 863 is 1
