Given numbers are 391, 407, 677, 525

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

Apply this formula for all numbers.

Step1:

LCM(391, 407) = 159137

GCD(391, 407) = ( 391 x 407 ) / 159137

= 391 / 407

= 391

Step2:

LCM(1, 677) = 677

GCD(1, 677) = ( 1 x 677 ) / 677

= 1 / 677

= 1

Step3:

LCM(1, 525) = 525

GCD(1, 525) = ( 1 x 525 ) / 525

= 1 / 525

= 1

So, Greatest Common Divisor of 391, 407, 677, 525 is 1
