Given numbers are 215, 770, 243, 419

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

Apply this formula for all numbers.

Step1:

LCM(215, 770) = 33110

GCD(215, 770) = ( 215 x 770 ) / 33110

= 215 / 770

= 215

Step2:

LCM(5, 243) = 1215

GCD(5, 243) = ( 5 x 243 ) / 1215

= 5 / 243

= 5

Step3:

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

= 1 / 419

= 1

So, Greatest Common Divisor of 215, 770, 243, 419 is 1
