Given numbers are 440, 115, 77, 494

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

Apply this formula for all numbers.

Step1:

LCM(440, 115) = 10120

GCD(440, 115) = ( 440 x 115 ) / 10120

= 440 / 115

= 440

Step2:

LCM(5, 77) = 385

GCD(5, 77) = ( 5 x 77 ) / 385

= 5 / 77

= 5

Step3:

LCM(1, 494) = 494

GCD(1, 494) = ( 1 x 494 ) / 494

= 1 / 494

= 1

So, Greatest Common Divisor of 440, 115, 77, 494 is 1
