Given numbers are 438, 207, 416, 121

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

Apply this formula for all numbers.

Step1:

LCM(438, 207) = 30222

GCD(438, 207) = ( 438 x 207 ) / 30222

= 438 / 207

= 438

Step2:

LCM(3, 416) = 1248

GCD(3, 416) = ( 3 x 416 ) / 1248

= 3 / 416

= 3

Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

So, Greatest Common Divisor of 438, 207, 416, 121 is 1
