Given numbers are 438, 321, 892, 915

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

Apply this formula for all numbers.

Step1:

LCM(438, 321) = 46866

GCD(438, 321) = ( 438 x 321 ) / 46866

= 438 / 321

= 438

Step2:

LCM(3, 892) = 2676

GCD(3, 892) = ( 3 x 892 ) / 2676

= 3 / 892

= 3

Step3:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

So, Greatest Common Divisor of 438, 321, 892, 915 is 1
