Given numbers are 145, 380, 521, 797

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

Apply this formula for all numbers.

Step1:

LCM(145, 380) = 11020

GCD(145, 380) = ( 145 x 380 ) / 11020

= 145 / 380

= 145

Step2:

LCM(5, 521) = 2605

GCD(5, 521) = ( 5 x 521 ) / 2605

= 5 / 521

= 5

Step3:

LCM(1, 797) = 797

GCD(1, 797) = ( 1 x 797 ) / 797

= 1 / 797

= 1

So, Greatest Common Divisor of 145, 380, 521, 797 is 1
