Given numbers are 254, 901, 642, 990

The list of prime factors of all numbers are

Prime factors of 254 are 2 x 127

Prime factors of 901 are 17 x 53

Prime factors of 642 are 2 x 3 x 107

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 254, 901, 642, 990

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

Apply this formula for all numbers.

Step1:

LCM(254, 901) = 228854

GCD(254, 901) = ( 254 x 901 ) / 228854

= 254 / 901

= 254

Step2:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

Step3:

LCM(1, 990) = 990

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

= 1 / 990

= 1

So, Greatest Common Divisor of 254, 901, 642, 990 is 1
