Given numbers are 438, 206, 607, 747

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

Apply this formula for all numbers.

Step1:

LCM(438, 206) = 45114

GCD(438, 206) = ( 438 x 206 ) / 45114

= 438 / 206

= 438

Step2:

LCM(2, 607) = 1214

GCD(2, 607) = ( 2 x 607 ) / 1214

= 2 / 607

= 2

Step3:

LCM(1, 747) = 747

GCD(1, 747) = ( 1 x 747 ) / 747

= 1 / 747

= 1

So, Greatest Common Divisor of 438, 206, 607, 747 is 1
