Given numbers are 509, 543, 781, 445

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

Apply this formula for all numbers.

Step1:

LCM(509, 543) = 276387

GCD(509, 543) = ( 509 x 543 ) / 276387

= 509 / 543

= 509

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

Step3:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

So, Greatest Common Divisor of 509, 543, 781, 445 is 1
