Given numbers are 545, 780, 163, 543

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

Apply this formula for all numbers.

Step1:

LCM(545, 780) = 85020

GCD(545, 780) = ( 545 x 780 ) / 85020

= 545 / 780

= 545

Step2:

LCM(5, 163) = 815

GCD(5, 163) = ( 5 x 163 ) / 815

= 5 / 163

= 5

Step3:

LCM(1, 543) = 543

GCD(1, 543) = ( 1 x 543 ) / 543

= 1 / 543

= 1

So, Greatest Common Divisor of 545, 780, 163, 543 is 1
