Given numbers are 215, 147, 909, 353

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

Apply this formula for all numbers.

Step1:

LCM(215, 147) = 31605

GCD(215, 147) = ( 215 x 147 ) / 31605

= 215 / 147

= 215

Step2:

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

= 1 / 909

= 1

Step3:

LCM(1, 353) = 353

GCD(1, 353) = ( 1 x 353 ) / 353

= 1 / 353

= 1

So, Greatest Common Divisor of 215, 147, 909, 353 is 1
