Given numbers are 148, 128, 122, 842

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

Apply this formula for all numbers.

Step1:

LCM(148, 128) = 4736

GCD(148, 128) = ( 148 x 128 ) / 4736

= 148 / 128

= 148

Step2:

LCM(4, 122) = 244

GCD(4, 122) = ( 4 x 122 ) / 244

= 4 / 122

= 4

Step3:

LCM(2, 842) = 842

GCD(2, 842) = ( 2 x 842 ) / 842

= 2 / 842

= 2

So, Greatest Common Divisor of 148, 128, 122, 842 is 2
