Given numbers are 545, 438, 853, 765

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

Apply this formula for all numbers.

Step1:

LCM(545, 438) = 238710

GCD(545, 438) = ( 545 x 438 ) / 238710

= 545 / 438

= 545

Step2:

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

= 1 / 853

= 1

Step3:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

So, Greatest Common Divisor of 545, 438, 853, 765 is 1
