Given numbers are 130, 103, 839, 658

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

Apply this formula for all numbers.

Step1:

LCM(130, 103) = 13390

GCD(130, 103) = ( 130 x 103 ) / 13390

= 130 / 103

= 130

Step2:

LCM(1, 839) = 839

GCD(1, 839) = ( 1 x 839 ) / 839

= 1 / 839

= 1

Step3:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 130, 103, 839, 658 is 1
