Given numbers are 654, 842, 990, 419

The list of prime factors of all numbers are

Prime factors of 654 are 2 x 3 x 109

Prime factors of 842 are 2 x 421

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

Prime factors of 419 are 419

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

Given numbers are 654, 842, 990, 419

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

Apply this formula for all numbers.

Step1:

LCM(654, 842) = 275334

GCD(654, 842) = ( 654 x 842 ) / 275334

= 654 / 842

= 654

Step2:

LCM(2, 990) = 990

GCD(2, 990) = ( 2 x 990 ) / 990

= 2 / 990

= 2

Step3:

LCM(2, 419) = 838

GCD(2, 419) = ( 2 x 419 ) / 838

= 2 / 419

= 2

So, Greatest Common Divisor of 654, 842, 990, 419 is 1
