Given numbers are 715, 830, 270, 215

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

Apply this formula for all numbers.

Step1:

LCM(715, 830) = 118690

GCD(715, 830) = ( 715 x 830 ) / 118690

= 715 / 830

= 715

Step2:

LCM(5, 270) = 270

GCD(5, 270) = ( 5 x 270 ) / 270

= 5 / 270

= 5

Step3:

LCM(5, 215) = 215

GCD(5, 215) = ( 5 x 215 ) / 215

= 5 / 215

= 5

So, Greatest Common Divisor of 715, 830, 270, 215 is 5
