Given numbers are 498, 656, 768, 661

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

Apply this formula for all numbers.

Step1:

LCM(498, 656) = 163344

GCD(498, 656) = ( 498 x 656 ) / 163344

= 498 / 656

= 498

Step2:

LCM(2, 768) = 768

GCD(2, 768) = ( 2 x 768 ) / 768

= 2 / 768

= 2

Step3:

LCM(2, 661) = 1322

GCD(2, 661) = ( 2 x 661 ) / 1322

= 2 / 661

= 2

So, Greatest Common Divisor of 498, 656, 768, 661 is 1
