Given numbers are 421, 237, 660, 407

The list of prime factors of all numbers are

Prime factors of 421 are 421

Prime factors of 237 are 3 x 79

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 407 are 11 x 37

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

Given numbers are 421, 237, 660, 407

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

Apply this formula for all numbers.

Step1:

LCM(421, 237) = 99777

GCD(421, 237) = ( 421 x 237 ) / 99777

= 421 / 237

= 421

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 421, 237, 660, 407 is 1
