Given numbers are 202, 105, 387, 668

The list of prime factors of all numbers are

Prime factors of 202 are 2 x 101

Prime factors of 105 are 3 x 5 x 7

Prime factors of 387 are 3 x 3 x 43

Prime factors of 668 are 2 x 2 x 167

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

Given numbers are 202, 105, 387, 668

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

Apply this formula for all numbers.

Step1:

LCM(202, 105) = 21210

GCD(202, 105) = ( 202 x 105 ) / 21210

= 202 / 105

= 202

Step2:

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

= 1 / 387

= 1

Step3:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

So, Greatest Common Divisor of 202, 105, 387, 668 is 1
