Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7
Prime factors of 781 are 11 x 71
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 785, 210, 756, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(785, 210) = 32970
GCD(785, 210) = ( 785 x 210 ) / 32970
= 785 / 210
= 785
Step2:
LCM(5, 756) = 3780
GCD(5, 756) = ( 5 x 756 ) / 3780
= 5 / 756
= 5
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 785, 210, 756, 781 is 1
