Steps to Calculate GCD of 987, 223, 388, 549 using LCM Formula

Given numbers are 987, 223, 388, 549

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

Apply this formula for all numbers.

Step1:

LCM(987, 223) = 220101

GCD(987, 223) = ( 987 x 223 ) / 220101

= 987 / 223

= 987


Step2:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1


Step3:

LCM(1, 549) = 549

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

= 1 / 549

= 1
