Given numbers are 290, 402, 641, 284

The list of prime factors of all numbers are

Prime factors of 290 are 2 x 5 x 29

Prime factors of 402 are 2 x 3 x 67

Prime factors of 641 are 641

Prime factors of 284 are 2 x 2 x 71

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

Given numbers are 290, 402, 641, 284

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

Apply this formula for all numbers.

Step1:

LCM(290, 402) = 58290

GCD(290, 402) = ( 290 x 402 ) / 58290

= 290 / 402

= 290

Step2:

LCM(2, 641) = 1282

GCD(2, 641) = ( 2 x 641 ) / 1282

= 2 / 641

= 2

Step3:

LCM(1, 284) = 284

GCD(1, 284) = ( 1 x 284 ) / 284

= 1 / 284

= 1

So, Greatest Common Divisor of 290, 402, 641, 284 is 1
