Given numbers are 516, 243, 747, 419

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

Apply this formula for all numbers.

Step1:

LCM(516, 243) = 41796

GCD(516, 243) = ( 516 x 243 ) / 41796

= 516 / 243

= 516

Step2:

LCM(3, 747) = 747

GCD(3, 747) = ( 3 x 747 ) / 747

= 3 / 747

= 3

Step3:

LCM(3, 419) = 1257

GCD(3, 419) = ( 3 x 419 ) / 1257

= 3 / 419

= 3

So, Greatest Common Divisor of 516, 243, 747, 419 is 1
