Given numbers are 644, 784, 198, 483

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

Apply this formula for all numbers.

Step1:

LCM(644, 784) = 18032

GCD(644, 784) = ( 644 x 784 ) / 18032

= 644 / 784

= 644

Step2:

LCM(28, 198) = 2772

GCD(28, 198) = ( 28 x 198 ) / 2772

= 28 / 198

= 28

Step3:

LCM(2, 483) = 966

GCD(2, 483) = ( 2 x 483 ) / 966

= 2 / 483

= 2

So, Greatest Common Divisor of 644, 784, 198, 483 is 1
