Given numbers are 660, 290, 381, 356

The list of prime factors of all numbers are

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

Prime factors of 290 are 2 x 5 x 29

Prime factors of 381 are 3 x 127

Prime factors of 356 are 2 x 2 x 89

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

Given numbers are 660, 290, 381, 356

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

Apply this formula for all numbers.

Step1:

LCM(660, 290) = 19140

GCD(660, 290) = ( 660 x 290 ) / 19140

= 660 / 290

= 660

Step2:

LCM(10, 381) = 3810

GCD(10, 381) = ( 10 x 381 ) / 3810

= 10 / 381

= 10

Step3:

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

= 1 / 356

= 1

So, Greatest Common Divisor of 660, 290, 381, 356 is 1
