Given numbers are 240, 618, 890, 665

The list of prime factors of all numbers are

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 618 are 2 x 3 x 103

Prime factors of 890 are 2 x 5 x 89

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 240, 618, 890, 665

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

Apply this formula for all numbers.

Step1:

LCM(240, 618) = 24720

GCD(240, 618) = ( 240 x 618 ) / 24720

= 240 / 618

= 240

Step2:

LCM(6, 890) = 2670

GCD(6, 890) = ( 6 x 890 ) / 2670

= 6 / 890

= 6

Step3:

LCM(2, 665) = 1330

GCD(2, 665) = ( 2 x 665 ) / 1330

= 2 / 665

= 2

So, Greatest Common Divisor of 240, 618, 890, 665 is 1
