Given numbers are 628, 622, 247, 842

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

Apply this formula for all numbers.

Step1:

LCM(628, 622) = 195308

GCD(628, 622) = ( 628 x 622 ) / 195308

= 628 / 622

= 628

Step2:

LCM(2, 247) = 494

GCD(2, 247) = ( 2 x 247 ) / 494

= 2 / 247

= 2

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 628, 622, 247, 842 is 1
