Given numbers are 513, 228, 20, 868

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

Apply this formula for all numbers.

Step1:

LCM(513, 228) = 2052

GCD(513, 228) = ( 513 x 228 ) / 2052

= 513 / 228

= 513

Step2:

LCM(57, 20) = 1140

GCD(57, 20) = ( 57 x 20 ) / 1140

= 57 / 20

= 57

Step3:

LCM(1, 868) = 868

GCD(1, 868) = ( 1 x 868 ) / 868

= 1 / 868

= 1

So, Greatest Common Divisor of 513, 228, 20, 868 is 1
