Given numbers are 645, 795, 722, 509

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

Apply this formula for all numbers.

Step1:

LCM(645, 795) = 34185

GCD(645, 795) = ( 645 x 795 ) / 34185

= 645 / 795

= 645

Step2:

LCM(15, 722) = 10830

GCD(15, 722) = ( 15 x 722 ) / 10830

= 15 / 722

= 15

Step3:

LCM(1, 509) = 509

GCD(1, 509) = ( 1 x 509 ) / 509

= 1 / 509

= 1

So, Greatest Common Divisor of 645, 795, 722, 509 is 1
