Given numbers are 291, 351, 137, 515

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

Apply this formula for all numbers.

Step1:

LCM(291, 351) = 34047

GCD(291, 351) = ( 291 x 351 ) / 34047

= 291 / 351

= 291

Step2:

LCM(3, 137) = 411

GCD(3, 137) = ( 3 x 137 ) / 411

= 3 / 137

= 3

Step3:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

So, Greatest Common Divisor of 291, 351, 137, 515 is 1
