Given numbers are 644, 940, 446, 429

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

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

Prime factors of 446 are 2 x 223

Prime factors of 429 are 3 x 11 x 13

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

Given numbers are 644, 940, 446, 429

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

Apply this formula for all numbers.

Step1:

LCM(644, 940) = 151340

GCD(644, 940) = ( 644 x 940 ) / 151340

= 644 / 940

= 644

Step2:

LCM(4, 446) = 892

GCD(4, 446) = ( 4 x 446 ) / 892

= 4 / 446

= 4

Step3:

LCM(2, 429) = 858

GCD(2, 429) = ( 2 x 429 ) / 858

= 2 / 429

= 2

So, Greatest Common Divisor of 644, 940, 446, 429 is 1
