Given numbers are 407, 664, 931, 549

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

Apply this formula for all numbers.

Step1:

LCM(407, 664) = 270248

GCD(407, 664) = ( 407 x 664 ) / 270248

= 407 / 664

= 407

Step2:

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

= 1 / 931

= 1

Step3:

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

= 1 / 549

= 1

So, Greatest Common Divisor of 407, 664, 931, 549 is 1
