Given numbers are 188, 140, 409, 660

The list of prime factors of all numbers are

Prime factors of 188 are 2 x 2 x 47

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 409 are 409

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

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

Given numbers are 188, 140, 409, 660

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

Apply this formula for all numbers.

Step1:

LCM(188, 140) = 6580

GCD(188, 140) = ( 188 x 140 ) / 6580

= 188 / 140

= 188

Step2:

LCM(4, 409) = 1636

GCD(4, 409) = ( 4 x 409 ) / 1636

= 4 / 409

= 4

Step3:

LCM(1, 660) = 660

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

= 1 / 660

= 1

So, Greatest Common Divisor of 188, 140, 409, 660 is 1
