Given numbers are 665, 820, 200, 154

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 200 are 2 x 2 x 2 x 5 x 5

Prime factors of 154 are 2 x 7 x 11

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

Given numbers are 665, 820, 200, 154

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

Apply this formula for all numbers.

Step1:

LCM(665, 820) = 109060

GCD(665, 820) = ( 665 x 820 ) / 109060

= 665 / 820

= 665

Step2:

LCM(5, 200) = 200

GCD(5, 200) = ( 5 x 200 ) / 200

= 5 / 200

= 5

Step3:

LCM(5, 154) = 770

GCD(5, 154) = ( 5 x 154 ) / 770

= 5 / 154

= 5

So, Greatest Common Divisor of 665, 820, 200, 154 is 1
