Given numbers are 730, 308, 128, 154

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

Apply this formula for all numbers.

Step1:

LCM(730, 308) = 112420

GCD(730, 308) = ( 730 x 308 ) / 112420

= 730 / 308

= 730

Step2:

LCM(2, 128) = 128

GCD(2, 128) = ( 2 x 128 ) / 128

= 2 / 128

= 2

Step3:

LCM(2, 154) = 154

GCD(2, 154) = ( 2 x 154 ) / 154

= 2 / 154

= 2

So, Greatest Common Divisor of 730, 308, 128, 154 is 2
