Given numbers are 438, 475, 361, 774

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

Apply this formula for all numbers.

Step1:

LCM(438, 475) = 208050

GCD(438, 475) = ( 438 x 475 ) / 208050

= 438 / 475

= 438

Step2:

LCM(1, 361) = 361

GCD(1, 361) = ( 1 x 361 ) / 361

= 1 / 361

= 1

Step3:

LCM(1, 774) = 774

GCD(1, 774) = ( 1 x 774 ) / 774

= 1 / 774

= 1

So, Greatest Common Divisor of 438, 475, 361, 774 is 1
