Given numbers are 145, 125, 897, 645

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

Apply this formula for all numbers.

Step1:

LCM(145, 125) = 3625

GCD(145, 125) = ( 145 x 125 ) / 3625

= 145 / 125

= 145

Step2:

LCM(5, 897) = 4485

GCD(5, 897) = ( 5 x 897 ) / 4485

= 5 / 897

= 5

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 145, 125, 897, 645 is 1
