Given numbers are 450, 156, 343, 655

The list of prime factors of all numbers are

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 343 are 7 x 7 x 7

Prime factors of 655 are 5 x 131

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

Given numbers are 450, 156, 343, 655

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

Apply this formula for all numbers.

Step1:

LCM(450, 156) = 11700

GCD(450, 156) = ( 450 x 156 ) / 11700

= 450 / 156

= 450

Step2:

LCM(6, 343) = 2058

GCD(6, 343) = ( 6 x 343 ) / 2058

= 6 / 343

= 6

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 450, 156, 343, 655 is 1
