Given numbers are 618, 849, 609, 221

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

Apply this formula for all numbers.

Step1:

LCM(618, 849) = 174894

GCD(618, 849) = ( 618 x 849 ) / 174894

= 618 / 849

= 618

Step2:

LCM(3, 609) = 609

GCD(3, 609) = ( 3 x 609 ) / 609

= 3 / 609

= 3

Step3:

LCM(3, 221) = 663

GCD(3, 221) = ( 3 x 221 ) / 663

= 3 / 221

= 3

So, Greatest Common Divisor of 618, 849, 609, 221 is 1
