Given numbers are 280, 155, 850, 198

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 155 are 5 x 31

Prime factors of 850 are 2 x 5 x 5 x 17

Prime factors of 198 are 2 x 3 x 3 x 11

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

Given numbers are 280, 155, 850, 198

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

Apply this formula for all numbers.

Step1:

LCM(280, 155) = 8680

GCD(280, 155) = ( 280 x 155 ) / 8680

= 280 / 155

= 280

Step2:

LCM(5, 850) = 850

GCD(5, 850) = ( 5 x 850 ) / 850

= 5 / 850

= 5

Step3:

LCM(5, 198) = 990

GCD(5, 198) = ( 5 x 198 ) / 990

= 5 / 198

= 5

So, Greatest Common Divisor of 280, 155, 850, 198 is 1
