Given numbers are 648, 780, 808, 219

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

Apply this formula for all numbers.

Step1:

LCM(648, 780) = 42120

GCD(648, 780) = ( 648 x 780 ) / 42120

= 648 / 780

= 648

Step2:

LCM(12, 808) = 2424

GCD(12, 808) = ( 12 x 808 ) / 2424

= 12 / 808

= 12

Step3:

LCM(4, 219) = 876

GCD(4, 219) = ( 4 x 219 ) / 876

= 4 / 219

= 4

So, Greatest Common Divisor of 648, 780, 808, 219 is 1
