Given numbers are 987, 352, 821, 672

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 352 are 2 x 2 x 2 x 2 x 2 x 11

Prime factors of 821 are 821

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 987, 352, 821, 672

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

Apply this formula for all numbers.

Step1:

LCM(987, 352) = 347424

GCD(987, 352) = ( 987 x 352 ) / 347424

= 987 / 352

= 987

Step2:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 987, 352, 821, 672 is 1
