Given numbers are 153, 639, 797, 399

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

Apply this formula for all numbers.

Step1:

LCM(153, 639) = 10863

GCD(153, 639) = ( 153 x 639 ) / 10863

= 153 / 639

= 153

Step2:

LCM(9, 797) = 7173

GCD(9, 797) = ( 9 x 797 ) / 7173

= 9 / 797

= 9

Step3:

LCM(1, 399) = 399

GCD(1, 399) = ( 1 x 399 ) / 399

= 1 / 399

= 1

So, Greatest Common Divisor of 153, 639, 797, 399 is 1
