Given numbers are 690, 154, 889, 783

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 154 are 2 x 7 x 11

Prime factors of 889 are 7 x 127

Prime factors of 783 are 3 x 3 x 3 x 29

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

Given numbers are 690, 154, 889, 783

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

Apply this formula for all numbers.

Step1:

LCM(690, 154) = 53130

GCD(690, 154) = ( 690 x 154 ) / 53130

= 690 / 154

= 690

Step2:

LCM(2, 889) = 1778

GCD(2, 889) = ( 2 x 889 ) / 1778

= 2 / 889

= 2

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 690, 154, 889, 783 is 1
