Given numbers are 391, 277, 306, 157

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

Apply this formula for all numbers.

Step1:

LCM(391, 277) = 108307

GCD(391, 277) = ( 391 x 277 ) / 108307

= 391 / 277

= 391

Step2:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

Step3:

LCM(1, 157) = 157

GCD(1, 157) = ( 1 x 157 ) / 157

= 1 / 157

= 1

So, Greatest Common Divisor of 391, 277, 306, 157 is 1
