Prime factors of 764 are 2 x 2 x 191
Prime factors of 173 are 173
Prime factors of 870 are 2 x 3 x 5 x 29
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 330, 764, 173, 870
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(330, 764) = 126060
GCD(330, 764) = ( 330 x 764 ) / 126060
= 330 / 764
= 330
Step2:
LCM(2, 173) = 346
GCD(2, 173) = ( 2 x 173 ) / 346
= 2 / 173
= 2
Step3:
LCM(1, 870) = 870
GCD(1, 870) = ( 1 x 870 ) / 870
= 1 / 870
= 1
So, Greatest Common Divisor of 330, 764, 173, 870 is 1
