Given numbers are 391, 375, 196, 775

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

Apply this formula for all numbers.

Step1:

LCM(391, 375) = 146625

GCD(391, 375) = ( 391 x 375 ) / 146625

= 391 / 375

= 391

Step2:

LCM(1, 196) = 196

GCD(1, 196) = ( 1 x 196 ) / 196

= 1 / 196

= 1

Step3:

LCM(1, 775) = 775

GCD(1, 775) = ( 1 x 775 ) / 775

= 1 / 775

= 1

So, Greatest Common Divisor of 391, 375, 196, 775 is 1
