Given numbers are 648, 516, 863, 728

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

Apply this formula for all numbers.

Step1:

LCM(648, 516) = 27864

GCD(648, 516) = ( 648 x 516 ) / 27864

= 648 / 516

= 648

Step2:

LCM(12, 863) = 10356

GCD(12, 863) = ( 12 x 863 ) / 10356

= 12 / 863

= 12

Step3:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

So, Greatest Common Divisor of 648, 516, 863, 728 is 1
