Given numbers are 672, 687, 485, 654
The list of prime factors of all numbers are
Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7
Prime factors of 687 are 3 x 229
Prime factors of 485 are 5 x 97
Prime factors of 654 are 2 x 3 x 109
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 672, 687, 485, 654
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(672, 687) = 153888
GCD(672, 687) = ( 672 x 687 ) / 153888
= 672 / 687
= 672
Step2:
LCM(3, 485) = 1455
GCD(3, 485) = ( 3 x 485 ) / 1455
= 3 / 485
= 3
Step3:
LCM(1, 654) = 654
GCD(1, 654) = ( 1 x 654 ) / 654
= 1 / 654
= 1
So, Greatest Common Divisor of 672, 687, 485, 654 is 1
