Given numbers are 145, 665, 441, 355

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

Apply this formula for all numbers.

Step1:

LCM(145, 665) = 19285

GCD(145, 665) = ( 145 x 665 ) / 19285

= 145 / 665

= 145

Step2:

LCM(5, 441) = 2205

GCD(5, 441) = ( 5 x 441 ) / 2205

= 5 / 441

= 5

Step3:

LCM(1, 355) = 355

GCD(1, 355) = ( 1 x 355 ) / 355

= 1 / 355

= 1

So, Greatest Common Divisor of 145, 665, 441, 355 is 1
