Prime factors of 447 are 3 x 149
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 812, 553, 858, 447
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(812, 553) = 64148
GCD(812, 553) = ( 812 x 553 ) / 64148
= 812 / 553
= 812
Step2:
LCM(7, 858) = 6006
GCD(7, 858) = ( 7 x 858 ) / 6006
= 7 / 858
= 7
Step3:
LCM(1, 447) = 447
GCD(1, 447) = ( 1 x 447 ) / 447
= 1 / 447
= 1
So, Greatest Common Divisor of 812, 553, 858, 447 is 1
