Given numbers are 445, 654, 910, 690

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 654 are 2 x 3 x 109

Prime factors of 910 are 2 x 5 x 7 x 13

Prime factors of 690 are 2 x 3 x 5 x 23

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

Given numbers are 445, 654, 910, 690

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

Apply this formula for all numbers.

Step1:

LCM(445, 654) = 291030

GCD(445, 654) = ( 445 x 654 ) / 291030

= 445 / 654

= 445

Step2:

LCM(1, 910) = 910

GCD(1, 910) = ( 1 x 910 ) / 910

= 1 / 910

= 1

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 445, 654, 910, 690 is 1
