Given numbers are 154, 803, 130, 438

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

Apply this formula for all numbers.

Step1:

LCM(154, 803) = 11242

GCD(154, 803) = ( 154 x 803 ) / 11242

= 154 / 803

= 154

Step2:

LCM(11, 130) = 1430

GCD(11, 130) = ( 11 x 130 ) / 1430

= 11 / 130

= 11

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 154, 803, 130, 438 is 1
