Given numbers are 393, 964, 578, 787

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

Apply this formula for all numbers.

Step1:

LCM(393, 964) = 378852

GCD(393, 964) = ( 393 x 964 ) / 378852

= 393 / 964

= 393

Step2:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

Step3:

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

= 1 / 787

= 1

So, Greatest Common Divisor of 393, 964, 578, 787 is 1
