Given numbers are 154, 315, 402, 648

The list of prime factors of all numbers are

Prime factors of 154 are 2 x 7 x 11

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 402 are 2 x 3 x 67

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 154, 315, 402, 648

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

Apply this formula for all numbers.

Step1:

LCM(154, 315) = 6930

GCD(154, 315) = ( 154 x 315 ) / 6930

= 154 / 315

= 154

Step2:

LCM(7, 402) = 2814

GCD(7, 402) = ( 7 x 402 ) / 2814

= 7 / 402

= 7

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 154, 315, 402, 648 is 1
