Given numbers are 473, 649, 438, 194

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

Apply this formula for all numbers.

Step1:

LCM(473, 649) = 27907

GCD(473, 649) = ( 473 x 649 ) / 27907

= 473 / 649

= 473

Step2:

LCM(11, 438) = 4818

GCD(11, 438) = ( 11 x 438 ) / 4818

= 11 / 438

= 11

Step3:

LCM(1, 194) = 194

GCD(1, 194) = ( 1 x 194 ) / 194

= 1 / 194

= 1

So, Greatest Common Divisor of 473, 649, 438, 194 is 1
