Given numbers are 455, 131, 378, 451

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 131 are 131

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 451 are 11 x 41

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

Given numbers are 455, 131, 378, 451

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

Apply this formula for all numbers.

Step1:

LCM(455, 131) = 59605

GCD(455, 131) = ( 455 x 131 ) / 59605

= 455 / 131

= 455

Step2:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

Step3:

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

= 1 / 451

= 1

So, Greatest Common Divisor of 455, 131, 378, 451 is 1
