Given numbers are 641, 660, 193, 378

The list of prime factors of all numbers are

Prime factors of 641 are 641

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 193 are 193

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

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

Given numbers are 641, 660, 193, 378

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

Apply this formula for all numbers.

Step1:

LCM(641, 660) = 423060

GCD(641, 660) = ( 641 x 660 ) / 423060

= 641 / 660

= 641

Step2:

LCM(1, 193) = 193

GCD(1, 193) = ( 1 x 193 ) / 193

= 1 / 193

= 1

Step3:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

So, Greatest Common Divisor of 641, 660, 193, 378 is 1
