Given numbers are 945, 639, 499, 399

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

Apply this formula for all numbers.

Step1:

LCM(945, 639) = 67095

GCD(945, 639) = ( 945 x 639 ) / 67095

= 945 / 639

= 945

Step2:

LCM(9, 499) = 4491

GCD(9, 499) = ( 9 x 499 ) / 4491

= 9 / 499

= 9

Step3:

LCM(1, 399) = 399

GCD(1, 399) = ( 1 x 399 ) / 399

= 1 / 399

= 1

So, Greatest Common Divisor of 945, 639, 499, 399 is 1
