Given numbers are 428, 940, 831, 654

The list of prime factors of all numbers are

Prime factors of 428 are 2 x 2 x 107

Prime factors of 940 are 2 x 2 x 5 x 47

Prime factors of 831 are 3 x 277

Prime factors of 654 are 2 x 3 x 109

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

Given numbers are 428, 940, 831, 654

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

Apply this formula for all numbers.

Step1:

LCM(428, 940) = 100580

GCD(428, 940) = ( 428 x 940 ) / 100580

= 428 / 940

= 428

Step2:

LCM(4, 831) = 3324

GCD(4, 831) = ( 4 x 831 ) / 3324

= 4 / 831

= 4

Step3:

LCM(1, 654) = 654

GCD(1, 654) = ( 1 x 654 ) / 654

= 1 / 654

= 1

So, Greatest Common Divisor of 428, 940, 831, 654 is 1
