Given numbers are 121, 215, 406, 783

The list of prime factors of all numbers are

Prime factors of 121 are 11 x 11

Prime factors of 215 are 5 x 43

Prime factors of 406 are 2 x 7 x 29

Prime factors of 783 are 3 x 3 x 3 x 29

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 121, 215, 406, 783

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

Apply this formula for all numbers.

Step1:

LCM(121, 215) = 26015

GCD(121, 215) = ( 121 x 215 ) / 26015

= 121 / 215

= 121

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 121, 215, 406, 783 is 1
