Prime factors of 638 are 2 x 11 x 29
Prime factors of 865 are 5 x 173
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 650, 712, 638, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(650, 712) = 231400
GCD(650, 712) = ( 650 x 712 ) / 231400
= 650 / 712
= 650
Step2:
LCM(2, 638) = 638
GCD(2, 638) = ( 2 x 638 ) / 638
= 2 / 638
= 2
Step3:
LCM(2, 865) = 1730
GCD(2, 865) = ( 2 x 865 ) / 1730
= 2 / 865
= 2
So, Greatest Common Divisor of 650, 712, 638, 865 is 1
