Given numbers are 291, 438, 547, 203

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

Apply this formula for all numbers.

Step1:

LCM(291, 438) = 42486

GCD(291, 438) = ( 291 x 438 ) / 42486

= 291 / 438

= 291

Step2:

LCM(3, 547) = 1641

GCD(3, 547) = ( 3 x 547 ) / 1641

= 3 / 547

= 3

Step3:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

So, Greatest Common Divisor of 291, 438, 547, 203 is 1
