The list of prime factors of all numbers are

Prime factors of 754 are 2 x 13 x 29

Prime factors of 642 are 2 x 3 x 107

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

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

Given numbers are 754, 642, 945, 990

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

Apply this formula for all numbers.

Step1:

LCM(754, 642) = 242034

GCD(754, 642) = ( 754 x 642 ) / 242034

= 754 / 642

= 754

Step2:

LCM(2, 945) = 1890

GCD(2, 945) = ( 2 x 945 ) / 1890

= 2 / 945

= 2

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 754, 642, 945, 990 is 1
