Given numbers are 144, 639, 608, 930

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

Apply this formula for all numbers.

Step1:

LCM(144, 639) = 10224

GCD(144, 639) = ( 144 x 639 ) / 10224

= 144 / 639

= 144

Step2:

LCM(9, 608) = 5472

GCD(9, 608) = ( 9 x 608 ) / 5472

= 9 / 608

= 9

Step3:

LCM(1, 930) = 930

GCD(1, 930) = ( 1 x 930 ) / 930

= 1 / 930

= 1

So, Greatest Common Divisor of 144, 639, 608, 930 is 1
