Given numbers are 145, 864, 870, 278

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 278 are 2 x 139

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

Given numbers are 145, 864, 870, 278

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

Apply this formula for all numbers.

Step1:

LCM(145, 864) = 125280

GCD(145, 864) = ( 145 x 864 ) / 125280

= 145 / 864

= 145

Step2:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

Step3:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

So, Greatest Common Divisor of 145, 864, 870, 278 is 1
