Given numbers are 655, 781, 949, 446

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

Apply this formula for all numbers.

Step1:

LCM(655, 781) = 511555

GCD(655, 781) = ( 655 x 781 ) / 511555

= 655 / 781

= 655

Step2:

LCM(1, 949) = 949

GCD(1, 949) = ( 1 x 949 ) / 949

= 1 / 949

= 1

Step3:

LCM(1, 446) = 446

GCD(1, 446) = ( 1 x 446 ) / 446

= 1 / 446

= 1

So, Greatest Common Divisor of 655, 781, 949, 446 is 1
