Given numbers are 645, 575, 823, 837

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

Apply this formula for all numbers.

Step1:

LCM(645, 575) = 74175

GCD(645, 575) = ( 645 x 575 ) / 74175

= 645 / 575

= 645

Step2:

LCM(5, 823) = 4115

GCD(5, 823) = ( 5 x 823 ) / 4115

= 5 / 823

= 5

Step3:

LCM(1, 837) = 837

GCD(1, 837) = ( 1 x 837 ) / 837

= 1 / 837

= 1

So, Greatest Common Divisor of 645, 575, 823, 837 is 1
