Given numbers are 661, 978, 482, 393

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

Apply this formula for all numbers.

Step1:

LCM(661, 978) = 646458

GCD(661, 978) = ( 661 x 978 ) / 646458

= 661 / 978

= 661

Step2:

LCM(1, 482) = 482

GCD(1, 482) = ( 1 x 482 ) / 482

= 1 / 482

= 1

Step3:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

So, Greatest Common Divisor of 661, 978, 482, 393 is 1
