Given numbers are 274, 640, 213, 990

The list of prime factors of all numbers are

Prime factors of 274 are 2 x 137

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 213 are 3 x 71

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

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

Given numbers are 274, 640, 213, 990

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

Apply this formula for all numbers.

Step1:

LCM(274, 640) = 87680

GCD(274, 640) = ( 274 x 640 ) / 87680

= 274 / 640

= 274

Step2:

LCM(2, 213) = 426

GCD(2, 213) = ( 2 x 213 ) / 426

= 2 / 213

= 2

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 274, 640, 213, 990 is 1
