Given numbers are 177, 409, 185, 840

The list of prime factors of all numbers are

Prime factors of 177 are 3 x 59

Prime factors of 409 are 409

Prime factors of 185 are 5 x 37

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 177, 409, 185, 840

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

Apply this formula for all numbers.

Step1:

LCM(177, 409) = 72393

GCD(177, 409) = ( 177 x 409 ) / 72393

= 177 / 409

= 177

Step2:

LCM(1, 185) = 185

GCD(1, 185) = ( 1 x 185 ) / 185

= 1 / 185

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 177, 409, 185, 840 is 1
