Given numbers are 658, 105, 756, 841

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 105 are 3 x 5 x 7

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 841 are 29 x 29

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

Given numbers are 658, 105, 756, 841

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

Apply this formula for all numbers.

Step1:

LCM(658, 105) = 9870

GCD(658, 105) = ( 658 x 105 ) / 9870

= 658 / 105

= 658

Step2:

LCM(7, 756) = 756

GCD(7, 756) = ( 7 x 756 ) / 756

= 7 / 756

= 7

Step3:

LCM(7, 841) = 5887

GCD(7, 841) = ( 7 x 841 ) / 5887

= 7 / 841

= 7

So, Greatest Common Divisor of 658, 105, 756, 841 is 1
