Given numbers are 645, 771, 179, 833

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

Apply this formula for all numbers.

Step1:

LCM(645, 771) = 165765

GCD(645, 771) = ( 645 x 771 ) / 165765

= 645 / 771

= 645

Step2:

LCM(3, 179) = 537

GCD(3, 179) = ( 3 x 179 ) / 537

= 3 / 179

= 3

Step3:

LCM(1, 833) = 833

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

= 1 / 833

= 1

So, Greatest Common Divisor of 645, 771, 179, 833 is 1
