Given numbers are 658, 320, 619, 786

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 619 are 619

Prime factors of 786 are 2 x 3 x 131

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

Given numbers are 658, 320, 619, 786

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

Apply this formula for all numbers.

Step1:

LCM(658, 320) = 105280

GCD(658, 320) = ( 658 x 320 ) / 105280

= 658 / 320

= 658

Step2:

LCM(2, 619) = 1238

GCD(2, 619) = ( 2 x 619 ) / 1238

= 2 / 619

= 2

Step3:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

So, Greatest Common Divisor of 658, 320, 619, 786 is 1
