Given numbers are 665, 783, 411, 320

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 783 are 3 x 3 x 3 x 29

Prime factors of 411 are 3 x 137

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 665, 783, 411, 320

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

Apply this formula for all numbers.

Step1:

LCM(665, 783) = 520695

GCD(665, 783) = ( 665 x 783 ) / 520695

= 665 / 783

= 665

Step2:

LCM(1, 411) = 411

GCD(1, 411) = ( 1 x 411 ) / 411

= 1 / 411

= 1

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 665, 783, 411, 320 is 1
