Given numbers are 438, 909, 546, 857

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 909 are 3 x 3 x 101

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 857 are 857

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

Given numbers are 438, 909, 546, 857

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

Apply this formula for all numbers.

Step1:

LCM(438, 909) = 132714

GCD(438, 909) = ( 438 x 909 ) / 132714

= 438 / 909

= 438

Step2:

LCM(3, 546) = 546

GCD(3, 546) = ( 3 x 546 ) / 546

= 3 / 546

= 3

Step3:

LCM(3, 857) = 2571

GCD(3, 857) = ( 3 x 857 ) / 2571

= 3 / 857

= 3

So, Greatest Common Divisor of 438, 909, 546, 857 is 1
