Given numbers are 715, 347, 621

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

Apply this formula for all numbers.

Step1:

LCM(715, 347) = 248105

GCD(715, 347) = ( 715 x 347 ) / 248105

= 715 / 347

= 715

Step2:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 715, 347, 621 is 1
