Given numbers are 438, 136, 361, 955

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

Apply this formula for all numbers.

Step1:

LCM(438, 136) = 29784

GCD(438, 136) = ( 438 x 136 ) / 29784

= 438 / 136

= 438

Step2:

LCM(2, 361) = 722

GCD(2, 361) = ( 2 x 361 ) / 722

= 2 / 361

= 2

Step3:

LCM(1, 955) = 955

GCD(1, 955) = ( 1 x 955 ) / 955

= 1 / 955

= 1

So, Greatest Common Divisor of 438, 136, 361, 955 is 1
