Given numbers are 637, 343, 645, 383

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

Apply this formula for all numbers.

Step1:

LCM(637, 343) = 4459

GCD(637, 343) = ( 637 x 343 ) / 4459

= 637 / 343

= 637

Step2:

LCM(49, 645) = 31605

GCD(49, 645) = ( 49 x 645 ) / 31605

= 49 / 645

= 49

Step3:

LCM(1, 383) = 383

GCD(1, 383) = ( 1 x 383 ) / 383

= 1 / 383

= 1

So, Greatest Common Divisor of 637, 343, 645, 383 is 1
