Given numbers are 648, 123, 196, 680

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

Apply this formula for all numbers.

Step1:

LCM(648, 123) = 26568

GCD(648, 123) = ( 648 x 123 ) / 26568

= 648 / 123

= 648

Step2:

LCM(3, 196) = 588

GCD(3, 196) = ( 3 x 196 ) / 588

= 3 / 196

= 3

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 648, 123, 196, 680 is 1
