Given numbers are 438, 825, 118, 521

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

Apply this formula for all numbers.

Step1:

LCM(438, 825) = 120450

GCD(438, 825) = ( 438 x 825 ) / 120450

= 438 / 825

= 438

Step2:

LCM(3, 118) = 354

GCD(3, 118) = ( 3 x 118 ) / 354

= 3 / 118

= 3

Step3:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

So, Greatest Common Divisor of 438, 825, 118, 521 is 1
