Given numbers are 645, 397, 49, 450

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

Apply this formula for all numbers.

Step1:

LCM(645, 397) = 256065

GCD(645, 397) = ( 645 x 397 ) / 256065

= 645 / 397

= 645

Step2:

LCM(1, 49) = 49

GCD(1, 49) = ( 1 x 49 ) / 49

= 1 / 49

= 1

Step3:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

So, Greatest Common Divisor of 645, 397, 49, 450 is 1
