Given numbers are 987, 621, 448, 735

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

Prime factors of 735 are 3 x 5 x 7 x 7

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

Given numbers are 987, 621, 448, 735

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

Apply this formula for all numbers.

Step1:

LCM(987, 621) = 204309

GCD(987, 621) = ( 987 x 621 ) / 204309

= 987 / 621

= 987

Step2:

LCM(3, 448) = 1344

GCD(3, 448) = ( 3 x 448 ) / 1344

= 3 / 448

= 3

Step3:

LCM(1, 735) = 735

GCD(1, 735) = ( 1 x 735 ) / 735

= 1 / 735

= 1

So, Greatest Common Divisor of 987, 621, 448, 735 is 1
