Given numbers are 628, 978, 190, 139

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

Apply this formula for all numbers.

Step1:

LCM(628, 978) = 307092

GCD(628, 978) = ( 628 x 978 ) / 307092

= 628 / 978

= 628

Step2:

LCM(2, 190) = 190

GCD(2, 190) = ( 2 x 190 ) / 190

= 2 / 190

= 2

Step3:

LCM(2, 139) = 278

GCD(2, 139) = ( 2 x 139 ) / 278

= 2 / 139

= 2

So, Greatest Common Divisor of 628, 978, 190, 139 is 1
