Given numbers are 771, 530, 438

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

Apply this formula for all numbers.

Step1:

LCM(771, 530) = 408630

GCD(771, 530) = ( 771 x 530 ) / 408630

= 771 / 530

= 771

Step2:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 771, 530, 438 is 1
