Given numbers are 755, 445, 13, 455

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

Apply this formula for all numbers.

Step1:

LCM(755, 445) = 67195

GCD(755, 445) = ( 755 x 445 ) / 67195

= 755 / 445

= 755

Step2:

LCM(5, 13) = 65

GCD(5, 13) = ( 5 x 13 ) / 65

= 5 / 13

= 5

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 755, 445, 13, 455 is 1
