Given numbers are 644, 393, 833, 416

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

Apply this formula for all numbers.

Step1:

LCM(644, 393) = 253092

GCD(644, 393) = ( 644 x 393 ) / 253092

= 644 / 393

= 644

Step2:

LCM(1, 833) = 833

GCD(1, 833) = ( 1 x 833 ) / 833

= 1 / 833

= 1

Step3:

LCM(1, 416) = 416

GCD(1, 416) = ( 1 x 416 ) / 416

= 1 / 416

= 1

So, Greatest Common Divisor of 644, 393, 833, 416 is 1
