Given numbers are 971, 140, 906, 490

The list of prime factors of all numbers are

Prime factors of 971 are 971

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 906 are 2 x 3 x 151

Prime factors of 490 are 2 x 5 x 7 x 7

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

Given numbers are 971, 140, 906, 490

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

Apply this formula for all numbers.

Step1:

LCM(971, 140) = 135940

GCD(971, 140) = ( 971 x 140 ) / 135940

= 971 / 140

= 971

Step2:

LCM(1, 906) = 906

GCD(1, 906) = ( 1 x 906 ) / 906

= 1 / 906

= 1

Step3:

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

= 1 / 490

= 1

So, Greatest Common Divisor of 971, 140, 906, 490 is 1
