Given numbers are 648, 884, 640, 538

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

Apply this formula for all numbers.

Step1:

LCM(648, 884) = 143208

GCD(648, 884) = ( 648 x 884 ) / 143208

= 648 / 884

= 648

Step2:

LCM(4, 640) = 640

GCD(4, 640) = ( 4 x 640 ) / 640

= 4 / 640

= 4

Step3:

LCM(4, 538) = 1076

GCD(4, 538) = ( 4 x 538 ) / 1076

= 4 / 538

= 4

So, Greatest Common Divisor of 648, 884, 640, 538 is 2
