Prime factors of 546 are 2 x 3 x 7 x 13
Prime factors of 247 are 13 x 19
Prime factors of 858 are 2 x 3 x 11 x 13
Prime factors of 685 are 5 x 137
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 546, 247, 858, 685
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(546, 247) = 10374
GCD(546, 247) = ( 546 x 247 ) / 10374
= 546 / 247
= 546
Step2:
LCM(13, 858) = 858
GCD(13, 858) = ( 13 x 858 ) / 858
= 13 / 858
= 13
Step3:
LCM(13, 685) = 8905
GCD(13, 685) = ( 13 x 685 ) / 8905
= 13 / 685
= 13
So, Greatest Common Divisor of 546, 247, 858, 685 is 1
