Given numbers are 513, 985, 783, 817

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

Apply this formula for all numbers.

Step1:

LCM(513, 985) = 505305

GCD(513, 985) = ( 513 x 985 ) / 505305

= 513 / 985

= 513

Step2:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

Step3:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

So, Greatest Common Divisor of 513, 985, 783, 817 is 1
