Given numbers are 153, 221, 587, 618

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

Apply this formula for all numbers.

Step1:

LCM(153, 221) = 1989

GCD(153, 221) = ( 153 x 221 ) / 1989

= 153 / 221

= 153

Step2:

LCM(17, 587) = 9979

GCD(17, 587) = ( 17 x 587 ) / 9979

= 17 / 587

= 17

Step3:

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

= 1 / 618

= 1

So, Greatest Common Divisor of 153, 221, 587, 618 is 1
