Given numbers are 513, 209, 947, 973

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

Apply this formula for all numbers.

Step1:

LCM(513, 209) = 5643

GCD(513, 209) = ( 513 x 209 ) / 5643

= 513 / 209

= 513

Step2:

LCM(19, 947) = 17993

GCD(19, 947) = ( 19 x 947 ) / 17993

= 19 / 947

= 19

Step3:

LCM(1, 973) = 973

GCD(1, 973) = ( 1 x 973 ) / 973

= 1 / 973

= 1

So, Greatest Common Divisor of 513, 209, 947, 973 is 1
