Given numbers are 513, 219, 156, 391

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

Apply this formula for all numbers.

Step1:

LCM(513, 219) = 37449

GCD(513, 219) = ( 513 x 219 ) / 37449

= 513 / 219

= 513

Step2:

LCM(3, 156) = 156

GCD(3, 156) = ( 3 x 156 ) / 156

= 3 / 156

= 3

Step3:

LCM(3, 391) = 1173

GCD(3, 391) = ( 3 x 391 ) / 1173

= 3 / 391

= 3

So, Greatest Common Divisor of 513, 219, 156, 391 is 1
