Given numbers are 690, 684, 644, 429

The list of prime factors of all numbers are

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

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 429 are 3 x 11 x 13

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

Given numbers are 690, 684, 644, 429

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

Apply this formula for all numbers.

Step1:

LCM(690, 684) = 78660

GCD(690, 684) = ( 690 x 684 ) / 78660

= 690 / 684

= 690

Step2:

LCM(6, 644) = 1932

GCD(6, 644) = ( 6 x 644 ) / 1932

= 6 / 644

= 6

Step3:

LCM(2, 429) = 858

GCD(2, 429) = ( 2 x 429 ) / 858

= 2 / 429

= 2

So, Greatest Common Divisor of 690, 684, 644, 429 is 1
