Given numbers are 290, 455, 972, 143

The list of prime factors of all numbers are

Prime factors of 290 are 2 x 5 x 29

Prime factors of 455 are 5 x 7 x 13

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 143 are 11 x 13

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

Given numbers are 290, 455, 972, 143

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

Apply this formula for all numbers.

Step1:

LCM(290, 455) = 26390

GCD(290, 455) = ( 290 x 455 ) / 26390

= 290 / 455

= 290

Step2:

LCM(5, 972) = 4860

GCD(5, 972) = ( 5 x 972 ) / 4860

= 5 / 972

= 5

Step3:

LCM(1, 143) = 143

GCD(1, 143) = ( 1 x 143 ) / 143

= 1 / 143

= 1

So, Greatest Common Divisor of 290, 455, 972, 143 is 1
