The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 811, 658, 730, 785
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(811, 658) = 533638
GCD(811, 658) = ( 811 x 658 ) / 533638
= 811 / 658
= 811
Step2:
LCM(1, 730) = 730
GCD(1, 730) = ( 1 x 730 ) / 730
= 1 / 730
= 1
Step3:
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
= 1 / 785
= 1
So, Greatest Common Divisor of 811, 658, 730, 785 is 1
