Given numbers are 648, 603, 108, 781

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

Apply this formula for all numbers.

Step1:

LCM(648, 603) = 43416

GCD(648, 603) = ( 648 x 603 ) / 43416

= 648 / 603

= 648

Step2:

LCM(9, 108) = 108

GCD(9, 108) = ( 9 x 108 ) / 108

= 9 / 108

= 9

Step3:

LCM(9, 781) = 7029

GCD(9, 781) = ( 9 x 781 ) / 7029

= 9 / 781

= 9

So, Greatest Common Divisor of 648, 603, 108, 781 is 1
