Given numbers are 411, 985, 638, 540

The list of prime factors of all numbers are

Prime factors of 411 are 3 x 137

Prime factors of 985 are 5 x 197

Prime factors of 638 are 2 x 11 x 29

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

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

Given numbers are 411, 985, 638, 540

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

Apply this formula for all numbers.

Step1:

LCM(411, 985) = 404835

GCD(411, 985) = ( 411 x 985 ) / 404835

= 411 / 985

= 411

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

= 1 / 540

= 1

So, Greatest Common Divisor of 411, 985, 638, 540 is 1
