Given numbers are 152, 178, 449, 842

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

Apply this formula for all numbers.

Step1:

LCM(152, 178) = 13528

GCD(152, 178) = ( 152 x 178 ) / 13528

= 152 / 178

= 152

Step2:

LCM(2, 449) = 898

GCD(2, 449) = ( 2 x 449 ) / 898

= 2 / 449

= 2

Step3:

LCM(1, 842) = 842

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

= 1 / 842

= 1

So, Greatest Common Divisor of 152, 178, 449, 842 is 1
