Given numbers are 221, 578, 654, 544

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

Apply this formula for all numbers.

Step1:

LCM(221, 578) = 7514

GCD(221, 578) = ( 221 x 578 ) / 7514

= 221 / 578

= 221

Step2:

LCM(17, 654) = 11118

GCD(17, 654) = ( 17 x 654 ) / 11118

= 17 / 654

= 17

Step3:

LCM(1, 544) = 544

GCD(1, 544) = ( 1 x 544 ) / 544

= 1 / 544

= 1

So, Greatest Common Divisor of 221, 578, 654, 544 is 1
