Given numbers are 868, 654, 487, 180

The list of prime factors of all numbers are

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 654 are 2 x 3 x 109

Prime factors of 487 are 487

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

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

Given numbers are 868, 654, 487, 180

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

Apply this formula for all numbers.

Step1:

LCM(868, 654) = 283836

GCD(868, 654) = ( 868 x 654 ) / 283836

= 868 / 654

= 868

Step2:

LCM(2, 487) = 974

GCD(2, 487) = ( 2 x 487 ) / 974

= 2 / 487

= 2

Step3:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

So, Greatest Common Divisor of 868, 654, 487, 180 is 1
