Given numbers are 215, 102, 100, 442

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 102 are 2 x 3 x 17

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 442 are 2 x 13 x 17

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

Given numbers are 215, 102, 100, 442

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

Apply this formula for all numbers.

Step1:

LCM(215, 102) = 21930

GCD(215, 102) = ( 215 x 102 ) / 21930

= 215 / 102

= 215

Step2:

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

= 1 / 100

= 1

Step3:

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

= 1 / 442

= 1

So, Greatest Common Divisor of 215, 102, 100, 442 is 1
