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

Apply this formula for all numbers.

Step1:

LCM(258, 732) = 31476

GCD(258, 732) = ( 258 x 732 ) / 31476

= 258 / 732

= 258

Step2:

LCM(6, 915) = 1830

GCD(6, 915) = ( 6 x 915 ) / 1830

= 6 / 915

= 6

Step3:

LCM(3, 687) = 687

GCD(3, 687) = ( 3 x 687 ) / 687

= 3 / 687

= 3

So, Greatest Common Divisor of 258, 732, 915, 687 is 3
