Given numbers are 720, 884, 278, 830

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

Apply this formula for all numbers.

Step1:

LCM(720, 884) = 159120

GCD(720, 884) = ( 720 x 884 ) / 159120

= 720 / 884

= 720

Step2:

LCM(4, 278) = 556

GCD(4, 278) = ( 4 x 278 ) / 556

= 4 / 278

= 4

Step3:

LCM(2, 830) = 830

GCD(2, 830) = ( 2 x 830 ) / 830

= 2 / 830

= 2

So, Greatest Common Divisor of 720, 884, 278, 830 is 2
