Given numbers are 648, 840, 795, 777

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

Apply this formula for all numbers.

Step1:

LCM(648, 840) = 22680

GCD(648, 840) = ( 648 x 840 ) / 22680

= 648 / 840

= 648

Step2:

LCM(24, 795) = 6360

GCD(24, 795) = ( 24 x 795 ) / 6360

= 24 / 795

= 24

Step3:

LCM(3, 777) = 777

GCD(3, 777) = ( 3 x 777 ) / 777

= 3 / 777

= 3

So, Greatest Common Divisor of 648, 840, 795, 777 is 3
