Given numbers are 478, 694, 764, 399

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

Apply this formula for all numbers.

Step1:

LCM(478, 694) = 165866

GCD(478, 694) = ( 478 x 694 ) / 165866

= 478 / 694

= 478

Step2:

LCM(2, 764) = 764

GCD(2, 764) = ( 2 x 764 ) / 764

= 2 / 764

= 2

Step3:

LCM(2, 399) = 798

GCD(2, 399) = ( 2 x 399 ) / 798

= 2 / 399

= 2

So, Greatest Common Divisor of 478, 694, 764, 399 is 1
