Given numbers are 139, 648, 257, 928

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

Apply this formula for all numbers.

Step1:

LCM(139, 648) = 90072

GCD(139, 648) = ( 139 x 648 ) / 90072

= 139 / 648

= 139

Step2:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

Step3:

LCM(1, 928) = 928

GCD(1, 928) = ( 1 x 928 ) / 928

= 1 / 928

= 1

So, Greatest Common Divisor of 139, 648, 257, 928 is 1
