Given numbers are 391, 261, 667, 101

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

Apply this formula for all numbers.

Step1:

LCM(391, 261) = 102051

GCD(391, 261) = ( 391 x 261 ) / 102051

= 391 / 261

= 391

Step2:

LCM(1, 667) = 667

GCD(1, 667) = ( 1 x 667 ) / 667

= 1 / 667

= 1

Step3:

LCM(1, 101) = 101

GCD(1, 101) = ( 1 x 101 ) / 101

= 1 / 101

= 1

So, Greatest Common Divisor of 391, 261, 667, 101 is 1
