Given numbers are 418, 145, 616, 987

The list of prime factors of all numbers are

Prime factors of 418 are 2 x 11 x 19

Prime factors of 145 are 5 x 29

Prime factors of 616 are 2 x 2 x 2 x 7 x 11

Prime factors of 987 are 3 x 7 x 47

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

Given numbers are 418, 145, 616, 987

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

Apply this formula for all numbers.

Step1:

LCM(418, 145) = 60610

GCD(418, 145) = ( 418 x 145 ) / 60610

= 418 / 145

= 418

Step2:

LCM(1, 616) = 616

GCD(1, 616) = ( 1 x 616 ) / 616

= 1 / 616

= 1

Step3:

LCM(1, 987) = 987

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

= 1 / 987

= 1

So, Greatest Common Divisor of 418, 145, 616, 987 is 1
