Prime factors of 832 are 2 x 2 x 2 x 2 x 2 x 2 x 13
Prime factors of 620 are 2 x 2 x 5 x 31
Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3
Prime factors of 645 are 3 x 5 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 832, 620, 432, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(832, 620) = 128960
GCD(832, 620) = ( 832 x 620 ) / 128960
= 832 / 620
= 832
Step2:
LCM(4, 432) = 432
GCD(4, 432) = ( 4 x 432 ) / 432
= 4 / 432
= 4
Step3:
LCM(4, 645) = 2580
GCD(4, 645) = ( 4 x 645 ) / 2580
= 4 / 645
= 4
So, Greatest Common Divisor of 832, 620, 432, 645 is 1
