Given numbers are 221, 658, 578, 526

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

Apply this formula for all numbers.

Step1:

LCM(221, 658) = 145418

GCD(221, 658) = ( 221 x 658 ) / 145418

= 221 / 658

= 221

Step2:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

Step3:

LCM(1, 526) = 526

GCD(1, 526) = ( 1 x 526 ) / 526

= 1 / 526

= 1

So, Greatest Common Divisor of 221, 658, 578, 526 is 1
