Given numbers are 768, 244, 949, 640

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

Apply this formula for all numbers.

Step1:

LCM(768, 244) = 46848

GCD(768, 244) = ( 768 x 244 ) / 46848

= 768 / 244

= 768

Step2:

LCM(4, 949) = 3796

GCD(4, 949) = ( 4 x 949 ) / 3796

= 4 / 949

= 4

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 768, 244, 949, 640 is 1
