Given numbers are 387, 472, 687, 549

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

Apply this formula for all numbers.

Step1:

LCM(387, 472) = 182664

GCD(387, 472) = ( 387 x 472 ) / 182664

= 387 / 472

= 387

Step2:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

Step3:

LCM(1, 549) = 549

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

= 1 / 549

= 1

So, Greatest Common Divisor of 387, 472, 687, 549 is 1
