Given numbers are 402, 909, 154, 828

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 909 are 3 x 3 x 101

Prime factors of 154 are 2 x 7 x 11

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

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

Given numbers are 402, 909, 154, 828

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

Apply this formula for all numbers.

Step1:

LCM(402, 909) = 121806

GCD(402, 909) = ( 402 x 909 ) / 121806

= 402 / 909

= 402

Step2:

LCM(3, 154) = 462

GCD(3, 154) = ( 3 x 154 ) / 462

= 3 / 154

= 3

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 402, 909, 154, 828 is 1
