Given numbers are 715, 291, 455

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

Apply this formula for all numbers.

Step1:

LCM(715, 291) = 208065

GCD(715, 291) = ( 715 x 291 ) / 208065

= 715 / 291

= 715

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 715, 291, 455 is 1
