Given numbers are 208, 821, 655, 244

The list of prime factors of all numbers are

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 821 are 821

Prime factors of 655 are 5 x 131

Prime factors of 244 are 2 x 2 x 61

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

Given numbers are 208, 821, 655, 244

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

Apply this formula for all numbers.

Step1:

LCM(208, 821) = 170768

GCD(208, 821) = ( 208 x 821 ) / 170768

= 208 / 821

= 208

Step2:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

Step3:

LCM(1, 244) = 244

GCD(1, 244) = ( 1 x 244 ) / 244

= 1 / 244

= 1

So, Greatest Common Divisor of 208, 821, 655, 244 is 1
