Given numbers are 515, 378, 987, 411

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 987 are 3 x 7 x 47

Prime factors of 411 are 3 x 137

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

Given numbers are 515, 378, 987, 411

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

Apply this formula for all numbers.

Step1:

LCM(515, 378) = 194670

GCD(515, 378) = ( 515 x 378 ) / 194670

= 515 / 378

= 515

Step2:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

Step3:

LCM(1, 411) = 411

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

= 1 / 411

= 1

So, Greatest Common Divisor of 515, 378, 987, 411 is 1
