Given numbers are 747, 459, 13, 380

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

Apply this formula for all numbers.

Step1:

LCM(747, 459) = 38097

GCD(747, 459) = ( 747 x 459 ) / 38097

= 747 / 459

= 747

Step2:

LCM(9, 13) = 117

GCD(9, 13) = ( 9 x 13 ) / 117

= 9 / 13

= 9

Step3:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

So, Greatest Common Divisor of 747, 459, 13, 380 is 1
