Given numbers are 720, 200, 778, 520

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

Apply this formula for all numbers.

Step1:

LCM(720, 200) = 3600

GCD(720, 200) = ( 720 x 200 ) / 3600

= 720 / 200

= 720

Step2:

LCM(40, 778) = 15560

GCD(40, 778) = ( 40 x 778 ) / 15560

= 40 / 778

= 40

Step3:

LCM(2, 520) = 520

GCD(2, 520) = ( 2 x 520 ) / 520

= 2 / 520

= 2

So, Greatest Common Divisor of 720, 200, 778, 520 is 2
