Given numbers are 645, 273, 289, 151

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

Apply this formula for all numbers.

Step1:

LCM(645, 273) = 58695

GCD(645, 273) = ( 645 x 273 ) / 58695

= 645 / 273

= 645

Step2:

LCM(3, 289) = 867

GCD(3, 289) = ( 3 x 289 ) / 867

= 3 / 289

= 3

Step3:

LCM(1, 151) = 151

GCD(1, 151) = ( 1 x 151 ) / 151

= 1 / 151

= 1

So, Greatest Common Divisor of 645, 273, 289, 151 is 1
