Given numbers are 418, 654, 945, 965

The list of prime factors of all numbers are

Prime factors of 418 are 2 x 11 x 19

Prime factors of 654 are 2 x 3 x 109

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 965 are 5 x 193

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

Given numbers are 418, 654, 945, 965

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

Apply this formula for all numbers.

Step1:

LCM(418, 654) = 136686

GCD(418, 654) = ( 418 x 654 ) / 136686

= 418 / 654

= 418

Step2:

LCM(2, 945) = 1890

GCD(2, 945) = ( 2 x 945 ) / 1890

= 2 / 945

= 2

Step3:

LCM(1, 965) = 965

GCD(1, 965) = ( 1 x 965 ) / 965

= 1 / 965

= 1

So, Greatest Common Divisor of 418, 654, 945, 965 is 1
