Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7
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 671, 515, 756, 870
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(671, 515) = 345565
GCD(671, 515) = ( 671 x 515 ) / 345565
= 671 / 515
= 671
Step2:
LCM(1, 756) = 756
GCD(1, 756) = ( 1 x 756 ) / 756
= 1 / 756
= 1
Step3:
LCM(1, 870) = 870
GCD(1, 870) = ( 1 x 870 ) / 870
= 1 / 870
= 1
So, Greatest Common Divisor of 671, 515, 756, 870 is 1
