Given numbers are 687, 498, 147, 730

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

Apply this formula for all numbers.

Step1:

LCM(687, 498) = 114042

GCD(687, 498) = ( 687 x 498 ) / 114042

= 687 / 498

= 687

Step2:

LCM(3, 147) = 147

GCD(3, 147) = ( 3 x 147 ) / 147

= 3 / 147

= 3

Step3:

LCM(3, 730) = 2190

GCD(3, 730) = ( 3 x 730 ) / 2190

= 3 / 730

= 3

So, Greatest Common Divisor of 687, 498, 147, 730 is 1
