Given numbers are 245, 966, 142, 217

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

Apply this formula for all numbers.

Step1:

LCM(245, 966) = 33810

GCD(245, 966) = ( 245 x 966 ) / 33810

= 245 / 966

= 245

Step2:

LCM(7, 142) = 994

GCD(7, 142) = ( 7 x 142 ) / 994

= 7 / 142

= 7

Step3:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

So, Greatest Common Divisor of 245, 966, 142, 217 is 1
