Given numbers are 642, 185, 702, 786

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 185 are 5 x 37

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

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 642, 185, 702, 786

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

Apply this formula for all numbers.

Step1:

LCM(642, 185) = 118770

GCD(642, 185) = ( 642 x 185 ) / 118770

= 642 / 185

= 642

Step2:

LCM(1, 702) = 702

GCD(1, 702) = ( 1 x 702 ) / 702

= 1 / 702

= 1

Step3:

LCM(1, 786) = 786

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

= 1 / 786

= 1

So, Greatest Common Divisor of 642, 185, 702, 786 is 1
