Given numbers are 105, 246, 664, 402

The list of prime factors of all numbers are

Prime factors of 105 are 3 x 5 x 7

Prime factors of 246 are 2 x 3 x 41

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 402 are 2 x 3 x 67

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

Given numbers are 105, 246, 664, 402

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

Apply this formula for all numbers.

Step1:

LCM(105, 246) = 8610

GCD(105, 246) = ( 105 x 246 ) / 8610

= 105 / 246

= 105

Step2:

LCM(3, 664) = 1992

GCD(3, 664) = ( 3 x 664 ) / 1992

= 3 / 664

= 3

Step3:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

So, Greatest Common Divisor of 105, 246, 664, 402 is 1
