Given numbers are 845, 115, 485, 778

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

Apply this formula for all numbers.

Step1:

LCM(845, 115) = 19435

GCD(845, 115) = ( 845 x 115 ) / 19435

= 845 / 115

= 845

Step2:

LCM(5, 485) = 485

GCD(5, 485) = ( 5 x 485 ) / 485

= 5 / 485

= 5

Step3:

LCM(5, 778) = 3890

GCD(5, 778) = ( 5 x 778 ) / 3890

= 5 / 778

= 5

So, Greatest Common Divisor of 845, 115, 485, 778 is 1
