Given numbers are 645, 789, 952, 281

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

Apply this formula for all numbers.

Step1:

LCM(645, 789) = 169635

GCD(645, 789) = ( 645 x 789 ) / 169635

= 645 / 789

= 645

Step2:

LCM(3, 952) = 2856

GCD(3, 952) = ( 3 x 952 ) / 2856

= 3 / 952

= 3

Step3:

LCM(1, 281) = 281

GCD(1, 281) = ( 1 x 281 ) / 281

= 1 / 281

= 1

So, Greatest Common Divisor of 645, 789, 952, 281 is 1
