Given numbers are 645, 142, 590

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

Apply this formula for all numbers.

Step1:

LCM(645, 142) = 91590

GCD(645, 142) = ( 645 x 142 ) / 91590

= 645 / 142

= 645

Step2:

LCM(1, 590) = 590

GCD(1, 590) = ( 1 x 590 ) / 590

= 1 / 590

= 1

So, Greatest Common Divisor of 645, 142, 590 is 1
