Given numbers are 715, 940, 815, 219

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

Apply this formula for all numbers.

Step1:

LCM(715, 940) = 134420

GCD(715, 940) = ( 715 x 940 ) / 134420

= 715 / 940

= 715

Step2:

LCM(5, 815) = 815

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

= 5 / 815

= 5

Step3:

LCM(5, 219) = 1095

GCD(5, 219) = ( 5 x 219 ) / 1095

= 5 / 219

= 5

So, Greatest Common Divisor of 715, 940, 815, 219 is 1
