Given numbers are 665, 945, 220, 414

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

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

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 414 are 2 x 3 x 3 x 23

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

Given numbers are 665, 945, 220, 414

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

Apply this formula for all numbers.

Step1:

LCM(665, 945) = 17955

GCD(665, 945) = ( 665 x 945 ) / 17955

= 665 / 945

= 665

Step2:

LCM(35, 220) = 1540

GCD(35, 220) = ( 35 x 220 ) / 1540

= 35 / 220

= 35

Step3:

LCM(5, 414) = 2070

GCD(5, 414) = ( 5 x 414 ) / 2070

= 5 / 414

= 5

So, Greatest Common Divisor of 665, 945, 220, 414 is 1
