Given numbers are 862, 378, 148, 455

The list of prime factors of all numbers are

Prime factors of 862 are 2 x 431

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

Prime factors of 148 are 2 x 2 x 37

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 862, 378, 148, 455

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

Apply this formula for all numbers.

Step1:

LCM(862, 378) = 162918

GCD(862, 378) = ( 862 x 378 ) / 162918

= 862 / 378

= 862

Step2:

LCM(2, 148) = 148

GCD(2, 148) = ( 2 x 148 ) / 148

= 2 / 148

= 2

Step3:

LCM(2, 455) = 910

GCD(2, 455) = ( 2 x 455 ) / 910

= 2 / 455

= 2

So, Greatest Common Divisor of 862, 378, 148, 455 is 1
