Given numbers are 158, 290, 395, 771

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

Apply this formula for all numbers.

Step1:

LCM(158, 290) = 22910

GCD(158, 290) = ( 158 x 290 ) / 22910

= 158 / 290

= 158

Step2:

LCM(2, 395) = 790

GCD(2, 395) = ( 2 x 395 ) / 790

= 2 / 395

= 2

Step3:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1

So, Greatest Common Divisor of 158, 290, 395, 771 is 1
