Given numbers are 648, 260, 660, 550

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

Apply this formula for all numbers.

Step1:

LCM(648, 260) = 42120

GCD(648, 260) = ( 648 x 260 ) / 42120

= 648 / 260

= 648

Step2:

LCM(4, 660) = 660

GCD(4, 660) = ( 4 x 660 ) / 660

= 4 / 660

= 4

Step3:

LCM(4, 550) = 1100

GCD(4, 550) = ( 4 x 550 ) / 1100

= 4 / 550

= 4

So, Greatest Common Divisor of 648, 260, 660, 550 is 2
