Given numbers are 399, 644, 883, 480

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

Apply this formula for all numbers.

Step1:

LCM(399, 644) = 36708

GCD(399, 644) = ( 399 x 644 ) / 36708

= 399 / 644

= 399

Step2:

LCM(7, 883) = 6181

GCD(7, 883) = ( 7 x 883 ) / 6181

= 7 / 883

= 7

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 399, 644, 883, 480 is 1
